Let’s talk about alcohol.
I am a family practice physician and I talk to people of all ages about alcohol. The current recommendation is no more than seven drinks a week for women and fourteen drinks a week for men, no saving it up for the weekend. No more than two drinks in one day for women and no more than three for men.
“What?” you say “No way. Come on, that’s ridiculous.”
My patients don’t say “That’s ridiculous.” After all, they are paying me to do a physical exam and a preventative exam. I am supposed to give them advice. But what is the basis for that?
One drink is defined as a regulation 12 oz beer or 6 ounces of wine or two ounces of hard liquor. If it is a high alcohol beer or wine or liquor, the amount is less.
It is NOT the liver doctors that have given us these numbers. It is the cardiologists, the heart doctors. One drink in women or two in men lowers blood pressure and in general, has good effects. Go over that daily and there is a rebound in blood pressure as the alcohol wears off. Alcohol works in the same way as benzodiazepines: it makes people less anxious and more relaxed and lowers inhibitions. Both alcohol and benzodiazepines are addictive for many people. That is, they develop tolerance, it takes more of the substance to have the same effects, more tolerance and then it takes more and more substance to try to feel half way normal.
Cardiologists qualify this recommendation as follows: there is no recommended daily amount of alcohol that is considered heart protective because there are too many alcoholics. The recommended daily amount of alcohol for an alcoholic is none. The recommended daily amount of alcohol for the general population is none.
Alcohol withdrawal can be very very dangerous medically. I think that the three most difficult things to quit are heroin (and all opiates), methamphetamines and cigarettes, but alcohol is more dangerous. In heroin withdrawal all of the pain receptors fire at once, so it is torture, but people don’t die. With serious alcohol withdrawal, the blood pressure skyrockets and the person can have seizures, a stroke, a heart attack, delerium tremens and can die. In the hospital, benzodiazepines are used to slow the withdrawal, replacing alcohol in a controlled manner.
Alcohol does more than affect the blood pressure. Over time, alcohol can damage the heart and lead to congestive heart failure.
Of course, you know that it can damage the liver and lead to cirrhosis. Cirrhosis is sneaky: as long as there are a few functioning liver cells, the lab work can look pretty normal. The liver makes proteins for the blood and makes proteins that allow our blood to clot. Once there aren’t enough healthy cells to make those proteins, alcoholics will bleed quite spectacularly. If the amount of the protein albumin in their blood is low, fluid leaks from the blood into the tissues: so whatever part is “dependent”, that is, lowest, will be swollen. Alcoholics can have legs with swelling where I can push with my finger and there is a two or three cm dimple. Alcohol also can lead to gastritis and ulcers. If someone can’t clot and they are vomiting blood from an ulcer, the doctor gets a tummyache too, from worrying. Ow. The liver is also supposed to filter all of the blood in the body. As the liver gets blocked with dead liver cells, the blood starts to bypass it. The bypass is through blood vessels in the stomach. Remember that person vomiting blood? The swollen vessels in the stomach are called varicies and we don’t like them to bleed. They are big and can bleed really really fast. The person can die. I don’t like transfusing and really don’t like transfusing 12 units of blood. In end stage alcoholism, the liver no longer lowers the blood level of ammonia. Ammonia crosses the blood brain barrier and poisons the brain. We haven’t even discussed the lack of vitamin B12 and thiamine which can cause unraveling of the myelin sheaths on the long fibers in the spinal cord: this means that the person gets permanent asterixis and “walks like a drunk” even when they are sober. I’m sure I haven’t remembered all of the consequences of alcohol, but that will do for now, right?
How much alcohol daily causes the above charming picture? We Don’t Know. Really. And it is not okay to do randomized double blinded clinical trials to find out. Same with pregnant women: we don’t know if there is a safe amount of alcohol during pregnancy and we bloody well can’t test it. It is safer not to drink while you are pregnant.
In clinic, I ask how much people drink. If they say 1-2 drinks daily, I ask what the drink is. Sometimes they look confused. I explain that I have one patient who has two drinks a day: however, it is a 12 ounce glass with a little ice and a lot of whiskey. I asked him to estimate how much whiskey and he said, “6-8 ounces.” That is, each glass is 6-8 ounces. His blood pressure is not under control and so far I feel like a failure as a doctor with him; he is NOT reducing the amount. In medical school, the two jokes were: How much alcohol is too much? More than your doctor drinks. And: How much does the patient drink? Double or triple what they tell us.
The popular word in college used to be that you could drink one drink an hour and still be “okay”. “Okay” to drive and it would wear off. Sorry, nope. Breathalyzers are now pretty cheap; buy one if you are drinking more than the 1-2 per day. And the college students that are binge drinking 6-8 or more drinks on Friday and Saturday: it DOES have long term effects and it IS doing damage.
Lastly, sleep and depression. If you are having trouble sleeping, don’t drink. No alcohol at all. Alcohol is a depressant. It helps people to fall asleep. But they do not have “normal sleep architecture” and it works AGAINST them staying asleep. People often wake up as the alcohol wears off. And the blood pressure is having that rebound, remember, and often their heart will race. That is withdrawal. If you are having trouble sleeping or you are depressed, do not take a depressant. It makes it worse.
I saw a nineteen year old in clinic who admitted to “occasional” heroin use. “But I’m not addicted,” she said. I said, “Well, that’s good. But I took care of a bunch of people undergoing heroin withdrawal while I was in residency and it looked like one of the most painful things on the planet. So I would advise you to quit while you are ahead.” I saw her a year later and she said, “When I tried to quit, it WAS hard. I was addicted and didn’t know it. I’m off now and I won’t go back.” So if you tell me, no problem, I can quit alcohol any time, I say more power to you. Show me. And if it’s harder than you think, get help.
