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

Maybe you should Talk to SomeoneMaybe you should Talk to Someone

Author: Lori Gottlieb

Maybe you should talk to someone is a genuine, funny, touching, and realistic memoir of one therapist, as she navigates a difficult time in her professional and personal life. I couldn’t put this book down. As a therapeutic counsellor myself, the book gave me a greater understanding of psychology and human behaviour. It is a vulnerable portrayal of a renowned psychotherapist, her therapist, and the clients lives that she discusses in the book – and how they influence her life. If you have any preconceived bias about the therapy profession, this book might give you a new perspective. I laughed whole-heartedly and I blinked back the tears on one occasion. I’m really pleased I read Maybe You Should Talk About Someone. If you’re a busy person, the audio version may be more practical for you.

OCD: tips for self-managementOCD: tips for self-management

People living with obsessive-compulsive disorder are encouraged to follow three general tips for effective self-management. They are: challenge the obsessive thoughts and compulsive behaviours (this includes use of distraction skills, and resisting the compulsion), maintain high self-care (you may need to put your needs first a lot – this is NOT selfishness or self-centredness), and reaching out for support. I want to clarify that I am not trained or qualified in OCD treatment – this is an extract from an article posted on the Australian Institute of Professional Counselling website.

The following information has been retrieved from AIPC Article Library | Self-help Strategies for OCD and OCPD. I think it’s also important to reinforce that if you have been living with OCD for years, you’re probably the expert on what is already most effective for you, and some of the following suggestions may make you roll your eyes. It can be very helpful/useful to talk to other people who live with OCD. They may understand your experience better than health workers, and this can be comforting, validating and healing.

Challenge the obsessive thoughts and compulsive behaviours. In addition to refocusing, the OCD client can learn to recognise and reduce stress. Some of the strategies here are counter-intuitive. You can urge clients to “go with the flow” by writing down obsessive thoughts, anticipating OCD urges, and creating “legitimate” worry periods. Tell them to:

Write down your obsessive thoughts or worries. Keep a pen and pad, laptop, tablet, or smartphone nearby. When the obsessive thoughts come, simply write them down. Keep writing as the urges continue, even if all you are doing is repeating the same phrases over and over. Writing helps you see how repetitive the obsessions are and also causes them to lose their power. As writing is harder than thinking, the obsessive thoughts will disappear sooner.

Anticipate OCD urges. You can help ease compulsive urges before they arise by anticipating them. For example, if you are a “checker” subtype, you can pay extra attention the first time you lock the window or turn off the jug, combining the action with creating a solid mental picture of yourself doing the action, and simultaneously telling yourself, “I can see that the window is now locked.” Later urges to check can then be more easily re-labelled as “just an obsessive thought”.

Create an OCD worry period. Rather than suppressing obsessions or compulsions, reschedule them. Give yourself one or two 10-minute “worry periods” each day, times you are allowed to freely devote to obsessing. During the periods, you are to focus only on negative thoughts or urges, without correcting them. At the end of the period, let the obsessive thoughts go and return to normal activities. The rest of the day is to be free of obsessions and compulsions. When the urges come during non-worry periods, write them down and agree to postpone dealing with them until the worry period. During the worry time, read the list and assess whether you still want to obsess on the items in it or not.

Create a tape of your OCD obsessions. Choose a specific worry or obsession and record it into a voice recorder, laptop or smartphone, recounting it exactly as it comes into your mind. Play the recording back to yourself over and over for a 45-minute period each day, until listening to it no longer causes you to feel highly distressed. This continuous confrontation of the obsession helps you to gradually become less anxious. When the anxiety of one worry has decreased significantly, you can repeat the exercise for a different obsession (Robinson et al, 2013).

Maintain good self-care. A healthy, balanced lifestyle plays an important role in managing OCD and the attendant anxiety (generally present with OCD, even though the disorder is no longer classified as an “anxiety disorder” per se), so the helpfulness of the following practices – truly not rocket science – cannot be underscored. Encourage OCD clients to:

  • Practice relaxation techniques, for at least 30 minutes a day, to avoid triggering symptoms.
  • Adopt healthy eating habits, beginning with a good breakfast followed by frequent small meals – with much whole grain, fruit and vegetable – throughout the day to avoid blood sugar lows and to boost serotonin.
  • Exercise regularly; it’s a natural anti-anxiety treatment. Get 30 minutes plus of aerobic activity most days.
  • Avoid alcohol and nicotine, as these increase anxiety after the initial effects wear off.
  • Get enough sleep; a lack of it exacerbates anxious thoughts and feelings (Robinson et al, 2013).

Reach out for support. Staying connected to family and friends is the best defense an OCD client can muster against intrusive obsessions and compulsive urges, because social isolation exacerbates symptoms. Talking about worries and urges makes them seem less threatening. Also, involving others in one’s treatment can help maintain motivation and guard against setbacks. To help remind the client that s/he is not alone in the struggle with OCD, ask him or her to consider joining a support group, where personal experiences are shared and attendees also learn from others facing similar problems.

OCPD: Self-help strategies for survival

For both the person diagnosed with OCPD and also for his family and friends, dealing with this disorder requires patience, compassion, and fortitude. To start with, the ego-syntonic nature of OCPD means that the person does not necessarily agree that he has anything wrong at all. For those who staunchly continue to insist that their relational problems arise because of others’ faults, treatment is complicated. Given the OCPD’s general world view of “I am correct; you are wrong”, the prognosis for change is often poor. Transformation is likely to occur only when the OCPD’s relational skills and outlook are shifted. This is not a job for medication (at least not for long and not alone), and yet psychotherapy is not always available. When it is, the OCPD is not always willing to avail himself of it.

Regardless of this less-than-ideal context for managing OCPD, there are some things that the client himself and also friends and family can do to alleviate some of the tension and conflict that goes with living with the disorder. As a therapist, you can encourage the client and those around him to utilise some of these strategies.

Bibliotherapy. It’s a good idea to read up on OCPD, not only in order to know what to expect, but also for tips in dealing with it. Your client may also come upon writings that link some behaviours and lifestyle choices to the disorder in ways not understood before. When comprehension deepens, so, too, does the prospect of compassion.

Gentle confrontation (agreed beforehand). While we agree that OCPD clients have a mammoth need to be right, those clients who truly seek to feel better may be willing to make agreements with family and friends in which OCPD behaviours, when noticed, are gently challenged; the operative word here is gently.

Self-insight through journalling or tape-recording. We noted above that many OCPD clients are intelligent, sensitive people. Thus, keeping a diary or making voice recordings to note anything upsetting, anxiety-provoking, overwhelming, or depressing is a step toward the self-insight that will eventually help to manage the disorder. Too, family and friends may agree to note their observations and share them in a constructive, non-confrontational manner.

Good self-care. OCPD is a disorder about exaggerated need for control, so keeping on an emotional even keel can help reduce the unconscious need to micro-manage all of life. Strategies to achieve this are listed above under Tip 2 for maintaining self-care with OCD. They revolve around the basic life efforts of practicing relaxation techniques, adopting healthy eating and exercise regimens, getting decent sleep, and avoiding excessive alcohol/drug consumption (the last is not hard for the OCPD).

Reaching out for help. OCPD individuals tend to be loners, and relationships are hard for them to build and maintain. Nevertheless, it is helpful to the ultimate reduction of OCPD-engendered tension to go for support. This can be in the form of self-help groups, informal support from partner, family, and friends, or even from joining online communities of people dealing with the disorder. Whatever the form of the support, it may be helpful for OCPD clients to own their places of dysfunction when they see others owning their imperfect humanness – and surviving (Robinson et al, 2013)!
