Hyponatremia: Alcohol relation
It’s been a few days since I last posted. My excuses: it’s the Christmas season. My son just had his tonsils out a week ago 😦 I’ve been horribly upset because I had cognitive testing to see how CPM/EPM has impacted my cognitive abilities.
My issues are with memory, concentration, communication. Anyway to make the longest story short, the neuropsychologist that administered the test decided I was faking and/or my issues weren’t related to CPM/EPM, but were being caused by stress and fatigue, because my results on things like memory, etc were way below normal, but my tests that test intelligence show I’m way above normal.
Most of you don’t know that much about me, so you might not understand why this really ticks me off. I wasn’t faking. I’m an A type personality. It’s not in my blood to do badly on a test, definitely not on purpose!!
I was hoping to take the MCAT before this all happened. I’m still hoping to take it, but it will literally take an hour or two to write these brief posts, so it will be difficult to take something like the MCAT. Thank God, I can catch my mistakes, but it takes me an hour or two of constantly reading and re-reading my post before I get it right. You can’t do this on a MCAT.
I’m not the same person I was a year ago. A lot of my CPM/EPM issues have improved, but one of the areas I’m experiencing the greatest frustration is with my cognitive abilities. I have a hard time remembering simple things.
Ok, see. I’m going off on a rant. I’m already way off the topic I wanted to discuss. So, I’m going to just leave it at that. At one point, hopefully soon, I will discuss my story, how this all happened, but right now, I want to discuss how alcohol impacts blood sodium.
Some of this information might have been posted about in previous blogs, but I honestly don’t remember. So forgive me if this is a bit redundant.
I was extremely surprised to find out that you do NOT have to be an alcoholic to develop hyponatremia or CPM! You have a higher chance of developing hyponatremia even if you have just one drink.
You have a much greater chance of developing CPM if you are an alcoholic or a recovering alcoholic than a person who has just consumed one drink.
Reasons why alcoholics develop hyponatremia:
A.) They vomit due to excessive alcohol intake.
B.) hypovolaemia is decreased blood volume/ blood plasma. This occurs in alcoholics because of vomiting. This also leads to secretion of ADH (helps control urine output) which causes a person to urinate less and leads to fluid retention. Also, it stimulates thirst mechanisms. This leads to an increase of fluid consumption and a decrease of urine output which essentially dilutes your blood and lowers your blood sodium level.
Hypovolaemia is not the same as dehydration. Dehydration is due to excess fluid loss, but hypovolaemia is characterized by a loss of sodium..which leads to hyponatremia.
C.) Excessive consumption of large amounts of alcohol, which is low in salt, along with being malnourished. This is called “beer potomania”.
D.) The less common cause is because of SIADH, syndrome of inappropriate antidiuretic hormone secretion. The body secretes too much ADH. This again leads to dilution of the sodium in the blood.
Ok, folks. Here’s the thing. Earlier, I posted that ADH is inhibited when you drink alcohol. Now, I’m saying it is produced in excess. I’m totally aware of this contradiction, but this is a contradiction that is published in the literature.
According to the NIH, it is inhibited. Check out this link below:
According to this published article, ADH is produced in excess. Check out this link below:
SO WTF?? I really don’t know. I’m going to say that with everything in the body there has to be balance, so I’m going to say that if a person starts to consume alcohol, ADH is inhibited. However, as alcohol consumption increases, ADH begins to be released excessively because the body has dumped a large amount of nutrients, etc due to the frequent urination and possible vomiting.
Let me see if this makes a bit more sense. If you consume a large amount of fluids, you pee more (less ADH is released)…what goes in, must come out. At some point, you can push that balance to the other extreme. At some point your body realizes that you’ve lost a lot of your nutrients and fluids (have become dehydrated), so your pituitary releases large amounts of ADH to try to maintain that balance. If you continue to consume liquids, at the same time you are releasing more ADH, then you dilute the system even more quickly.
So, that’s my opinion, and I’m guessing that’s why there’s a contradiction in how ADH is impacted when you consume alcohol…but this is just my opinion. I will try to find some more clarifying information regarding it.
I hope you find it helpful or at least inspiring to do your own research.
