What Alcohol does to the Human Body

1. Alcohol (ethanol) enters the body through the oral cavity (i.e., the mouth). The inner surface of the oral cavity is mucosal tissue to keep the cavity lubricated and it is capable of absorbing alcohol into the bloodstream. This absorption is considered “insignificant”.

2. Alcohol flows down the oesophagus to the stomach where 10-20% of ethanol will be absorbed into the bloodstream. Alcohol enters the bloodstream via the mucosal tissue of the stomach wall, and travels straight to the liver. Alcohol can take 5-10 minutes to reach the brain because of the ethanol absorbed via the stomach. If you drink alcohol on an empty stomach, the pyloric sphincter [gateway between the stomach and the small intestine] is going to be more open, and the alcohol is going to immediately enter the small intestine after reaching the stomach. If food is also present in the stomach, the sphincter will open and close at a rate that allows food to enter the small intestine gradually, therefore if alcohol is also in the stomach, it will gradually enter the small intestine.

3. Alcohol flows through the pyloric sphincter into the small intestines where most alcohol absorption occurs. Human intestines are attached the to the posterior abdominal wall by a fold of membrane called the mesentery. Alcohol is absorbed into the mesentery via veins and then travels to the liver.

4. One function of the liver is that it detoxifies toxic elements into non-toxic elements before passing it to the heart and then the rest of the body. The liver sustains considerable “abuse” from a variety of toxic elements and chemicals, and therefore it needs to be capable of full regeneration. NOTE: Many diseases and exposures can harm it beyond the point of repair. These include cancer, hepatitis, certain medication overdoses, and fatty liver disease.

In the liver, ethanol is met with an enzyme called alcohol dehydrogenase and converts ethanol into acetaldehyde [ass-eh-tal-de-hide]. This chemical is more toxic than ethanol, so the liver uses another enzyme to convert acetaldehyde into acetate, which is non-toxic to the human body. NOTE: the amount of alcohol consumed + the timeframe it is consumed [and a variety of other factors] will influence the ability of the liver to effectively convert acetaldehyde all the way into acetate. The liver can’t handle the entire workload effectively therefore ethanol (before being metabolised) will go straight from the liver to the bloodstream and make its way directly to the heart.

NOTE: Genetics will play a role! Certain people do not produce the liver enzymes in enough quantity to properly breakdown ethanol.

5. Blood leaves the liver through the hepatic veins. The hepatic veins carry blood to the inferior vena cava—the largest vein in the body—to the right side of the heart. The heart will beat and send the incoming blood to the lungs to oxygenate and expel carbon dioxide as we breath out. This is how ethanol can be on your breath. Inside the lungs, at the very end of the bronchioles, are hollow air sacs called alveoli where there is a gas exchange. Ethanol evaporates through capillaries into the air sacs and exhaled out of the body. Breathalysers can detect the quantity of ethanol in a person’s system based on the quantity of ethanol in our breath.

6. Not all the ethanol will expel from the body via the breath. The rest will flow back to the heart, with newly oxygenated blood, and then get pumped all the way up to the brain and around the body. NOTE: Ethanol is water soluble. It will be distributed to every cell in the body except bone and fatty tissue [some will enter fat cells but not easily]. Ethanol will interact with every other cell i.e., every organ, gland, nerve, muscle etc.

7. Ethanol will affect and compromise protein synthesis inside muscle tissue. Therefore, if you have been training at the gym, running, swimming etc., your muscles will not effectively be able to repair.

8. Once ethanol has reached the brain, it will cross the blood-brain barrier and begin to affect chemical messengers [neurotransmitters] in the grey matter of the brain. It affects serotonin, dopamine, gamma-amino-butyric-acid (aka GABA), glutamate, endorphins etc. The person will experience pleasure, euphoria, lowered inhibitions [related to dopamine], lowered cognitive ability (e.g., decision making/problem solving, emotion regulation) and lowered coordination and reflexes.

The more ethanol ingested, the more dopamine is secreted and communicated between neurons (i.e., nerve cells). One of dopamine’s functions is to make you feel pleasure or ‘rewarded’ for doing things that are good for humans, hence, from an evolutionary perspective, we are likely to do them again to help us thrive in our environment and social world. Dopamine is secreted when we:

  • eat healthy foods (but also recently developed processed foods that are high in sugar and salt)
  • exercise
  • achieve goals
  • be productive (e.g., finish a task like cleaning, cooking, work-related tasks)
  • master new skills (e.g., learning an instrument or a new talent), and
  • have positive and stimulating social interactions

Ethanol influences so much dopamine secretion and communication that the brain becomes unable to make responsible decisions cognitively. The simultaneous experience of euphoria and lowered cognitive ability means we are more likely to be “happy” about making irresponsible decisions.

Increased dopamine is how drinking alcohol “blocks” unpleasant emotions like fear, stress, anxiety, and insecurity. When we don’t feel these unpleasant, yet necessary, emotions we will behave in ways that are dangerous, abnormal, potentially embarrassing, and generally problematic.

Another significant brain region affected by ethanol is the hypothalamus and the pituitary glad [together known as the hypothalamic-pituitary axis]. These structures control the entire hormonal system. The hypothalamus monitors the body, and it will send instructions to the pituitary gland based on information it receives from the hypothalamus. The hypothalamus is aware that ethanol is flooding the brain and it starts adjusting the secretion of hormones via the pituitary gland.

One of the instructions it gives the pituitary gland is to start modulating the adrenal glands to secrete cortisol (i.e., stress hormone) and epinephrine and norepinephrine (i.e., adrenaline).

Now, our cognitive capacity is diminished, inhibitions are lowered, and we will experience a rush of stress hormones and adrenaline coursing through the body. Cortisol and adrenaline will provide a boost of energy. It will increase the heart rate, blood pressure, body sweat, sugar levels in the bloodstream, and enhances the brain’s ability to use glucose. Glucose is a “fuel” source for brain functioning, including the generation of neurotransmitters. Behaviourally, we can see this in children when we say they are “hyperactive” because they’ve ingested too much sugar.

The pituitary gland will also slow the secretion of anti-diuretic hormone (aka. vasopressin). A diuretic is something that makes us urinate. If the anti-diuretic hormone (also called vasopressin) slows down, then we won’t be “holding on” to water as effectively, hence we begin to urinate more. People call this “breaking the seal”.

9. South of the body, blood is pumped into the kidneys via the renal artery which spreads through the renal cortex. The blood is then filtered into urine and expelled from the body. The lowered anti-diuretic hormone will dilate (become wider/bigger or more open) blood vessels in the kidneys which means more blood gets passed through and filtered, but it also means we lose a lot more body water which leads to dehydration. Vasopressin is essential in the control of osmotic balance, blood pressure regulations, and kidney function, therefore, when vasopressin is lowered, we are losing essential water and minerals/electrolytes. Electrolytes are involved in urination because the kidneys need them to make the process of filtering blood more efficient.

The loss of water and electrolytes will contribute to a hangover. Electrolytes play a role in cellular water absorption so if we are losing more water than we are bringing in, and we are losing the electrolytes that support the absorption of water, we become dehydrated very quickly.

10. The Hangover

Symptoms: nausea, fatigue, diarrhoea, vomiting, paranoia, anxiety, anorexia (i.e., loss of appetite), increased thirst, muscle weakness, irritability, sweating, increased blood pressure, and headache.

The exact cause of a “hangover” is not yet known however variables affecting the hangover are:

  • individual differences such as sex, size, body fat, genetics etc
  • lack of sleep
  • general health
  • drinking behaviour e.g., frequency, duration, quantity
  • food intake before and during
  • water intake before and after
  • your body’s ability to metabolise alcohol i.e., excessive amounts of acetaldehyde due to fewer enzymes to metabolise alcohol in the liver before entering the bloodstream
  • general behaviour while drinking e.g., poly-substance use, dancing, sexual activity, risk-taking behaviours etc.

Strategies for Controlled Drinking

  • Setting personal drinking limits and sticking to it
  • Alternating alcoholic drinks with soft drinks i.e., one alcoholic drink then a water, soft drink, or juice
  • Have a meal before drinking
  • Switching to low alcohol drinks
  • Having regular alcohol-free days/weeks/months
  • Identifying high risk situations for heavy drinking and creating a management plan

Engaging in alternative activities to drinking

Unhelpful Cognitions

Mental Filter: This thinking style involves a “filtering in” and “filtering out” process – a sort of “tunnel vision”, focusing on only one part of a situation and ignoring the rest. Usually this means looking at the negative parts of a situation and forgetting the positive parts, and the whole picture is coloured by what may be a single negative detail.

Jumping to Conclusions: We jump to conclusions when we assume that we know what someone else is thinking (mind reading) and when we make predictions about what is going to happen in the future (predictive thinking).

Mind reading: Is a habitual thinking pattern characterized by expecting others to know what you’re thinking without having to tell them or expecting to know what others are thinking without them telling you. This is very common, and most people can identify. Oftentimes, when we are telling someone a story about an interaction, we’ve had with someone else, we will make mind reading assumptions without actually having fact or evidence e.g., “They haven’t phoned me in two weeks so they must be angry with me for cancelling on them last week.”

Personalisation: This involves blaming yourself for everything that goes wrong or could go wrong, even when you may only be partly responsible or not responsible at all. You might be taking 100% responsibility for the occurrence of external events. It can also involve blaming someone else for something for which they have no responsibility. This can often occur when setting a boundary with someone and you take responsibility for their guilt or anger.

Catastrophising: Catastrophising occurs when we “blow things out of proportion” and we view the situation as terrible, awful, dreadful, and horrible, even though the reality is that the problem itself may be quite small.

Black & White Thinking: Also known as splitting, dichotomous thinking, and all-or-nothing thinking, involves seeing only one side or the other (the positives or the negatives, for example). You are either wrong or right, good or bad and so on. There are no in-betweens or shades of grey.

Should-ing and Must-ing: Sometimes by saying “I should…” or “I must…” you can put unreasonable demands or pressure on yourself and others. Although these statements are not always unhelpful (e.g., “I should not get drunk and drive home”), they can sometimes create unrealistic expectations.

Should-ing and must-ing can be a psychological distortion because it can “deny reality” e.g., I shouldn’t have had so much to drink last night. This is helpful in the sense that it communicates to us that we have exceeded our boundaries, however, saying “shouldn’t” about a past situation can be futile because it cannot be changed.

Overgeneralisation: When we overgeneralise, we take one instance in the past or present, and impose it on all current or future situations. If we say, “You always…” or “Everyone…”, or “I never…” then we are probably overgeneralising.

Labelling: We label ourselves and others when we make global statements based on behaviour in specific situations. We might use this label even though there are many more examples that are not consistent with that label. Labelling is a cognitive distortion whereby we take one characteristic of a person/group/situation and apply it to the whole person/group/situation. Example: “Because I failed a test, I am a failure” or “Because she is frequently late to work, she is irresponsible”.

Emotional Reasoning: This thinking style involves basing your view of situations or yourself on the way you are feeling. For example, the only evidence that something bad is going to happen is that you feel like something bad is going to happen. Emotions and feelings are real however they are not necessarily indicative of objective truth or fact.

Magnification and Minimisation: In this thinking style, you magnify the positive attributes of other people and minimise your own positive attributes. Also known as the binocular effect on thinking. Often it means that you enlarge (magnify) the positive attributes of other people and shrink (minimise) your own attributes, just like looking at the world through either end of the same pair of binoculars.

Acceptance and Commitment Therapy (ACT)Acceptance and Commitment Therapy (ACT)

I was recently browsing some of the units I completed for my counselling diploma – for revision. The human memory has not evolved to store, organise, categorise and recall all the large amounts of information we collect every day, nor is our memory always accurate. It’s important for counsellors and therapists to keep up to date with new approaches to counselling, and it doesn’t hurt to read over learned materials from college days. I thought I’d provide some learning about Acceptance and Commitment Therapy for readers.

Just to acknowledge the work of others, most of what is written below, I have retrieved and paraphrased from ACCEPTANCE AND COMMITMENT THERAPY Published by: Australian Institute of Professional Counsellors Pty Ltd.

Acceptance and commitment therapy, known as ACT (pronounced as the word ‘act’), is an approach to counselling that was originally developed in the early 1980s by Steven C. Hayes, and became popular in the early 2000’s through Hayes’ collaboration with Kelly G. Wilson, and Kirk Strosahl as well as through the work of Russ Harris. You can look them up on Youtube or Google if you’re interested in what they might have to say about ACT.

“Unlike more traditional cognitive-behaviour therapy (CBT) approaches, ACT does not
seek to change the form or frequency of people’s unwanted thoughts and emotions. Rather,
the principal goal of ACT is to cultivate psychological flexibility, which refers to the ability to
contact the present moment, and based on what the situation affords, to change or persist
with behaviour in accordance with one’s personal values. To put it another way, ACT
focuses on helping people to live more rewarding lives even in the presence of undesirable
thoughts, emotions, and sensations.”

(Flaxman, Blackledge & Bond, 2011, p. vii)

ACT interventions tend to focus around two main processes:

  • Developing acceptance of unwanted private experiences that are outside of personal
    control.
  • Commitment and action toward living a valued life (Harris, 2009)

In a nutshell, ACT gets its name from its core ideas of accepting what is outside of your personal control and committing to action that improves and enriches your life.

Cognitive Defusion is the process of learning to detach ourselves from our thought processes and simply observe them for what they are – “transient private events – an ever-changing stream of words, sounds and pictures” (Harris, 2006, p. 6). I think this component of ACT is incredibly beneficial if we practice it daily. I like to say, just like the function of the heart is to pump oxygenated blood around the body, one of the brain’s functions is to have thoughts. We can observe thoughts without taking them to mean more than what they are. Some thoughts are automatic, some are subconscious, and some are unconscious or preconscious beliefs that we consider to be true and factual and “rules” about how the world operates and how we have to operate in it. If someone is defused from their thought processes, these processes do not have control on the person; instead the person is able to simply observe them without getting caught up in them or feel the need to change/control them.

Acceptance is the process of opening oneself up and “making room for unpleasant feelings, sensations, urges, and other private experiences; allowing them to come and go without struggling with them, running from them, or giving them undue attention” (Harris, 2006, p. 7). Practicing acceptance is important because it encourages the individual to develop an ability and willingness to feel uncomfortable without being overwhelmed by it (Flaxman, Blackledge & Bond, 2011). It’s important to acknowledge that to accept something doesn’t mean we like it or have a passive attitude. It is to accept something exactly as it is and then we choose what to do with it. Think of the Serenity Prayer: Grant me the serenity to accept the things I cannot change, courage to change the things I can, and wisdom to know the difference.

Contact with the present moment is the concept of being “psychologically present” and bringing full attention to the “here-and-now” experience (Harris, 2009). I’d also argue that to psychologically present, we must also be aware of our physical body and the sensations within it and outside of it. Because we have the ability to think about the past and about the future, sometimes it can be difficult to stay in the present (Batten, 2011; Harris, 2009). Having contact with the present moment is essential because that it where we find out anchor and power. We have the ability to pay attention in a flexible manner to the present moment and connect with that experience rather than ruminate on past events or future possibilities (Lloyd & Bond, 2015). Some of you might say “What if I can’t stand the present moment?”. True. If you have extreme emotional experiences or have a history of trauma, it may be functional for you to use distraction or talking to someone when the present moment is “too much to take”. What we want to work towards is using healthy coping strategies in the present moment mindfully, instead of behaviours that no longer serve us.

Values, and identifying them, (i.e., what is important to the individual) is a central element of ACT because it assists clients to move in the direction of living and creating a meaningful life. One of the central goals of ACT is to help clients to connect with the things they value most and to travel in “valued directions” (Stoddard & Afari, 2014).

Committed action is the process of taking steps towards one’s values even in the presence of unpleasant thoughts and feelings (Harris, 2009). Behavioural interventions, such as goal setting, exposure, behavioural activation, and skills training, are generally used to create committed action. The ACT model acknowledges that learning is not enough, one must also take action to create change.

Self-as-context, or what I prefer to call “the observing self” or simply just our self-awareness, creates a distinction between the ‘thinking self’ and the ‘observing self’ (Harris, 2009). The thinking self refers to the self that generates thoughts, beliefs, memories, judgments, fantasies, and plans, whereas the observing self is the self that is aware of what we think, feel, sense, or do (Harris, 2009). “From this perspective, you are not your thoughts and feelings; rather, you are the context or arena in which they unfold” (Stoddard & Afari, 2014). Being aware of the observing self allows an individual to have a greater ability to be mindful and in the present moment, as they can separate themselves from the thoughts, beliefs, and memories they have.
