Can you get diarrhea by drinking too much water?

Can you get diarrhea by drinking too much water?

Generally no: The body has mechanisms to get rid of the excess water, but under certain conditions - if it is taken in very rapidly or in certain disease states, it can cause water intoxication - diluting the blood so that sodium levels can get very low - if low enough, it can cause seizures, coma and death. Diarrhea rarely occurs, because the water is absorbed in stomach and upper intestine, but it can.

It can also be a psychological problem called "pathological water drinker." the main point here is that electrolytes, esp. Sodium need to stay in balance. Excessive drinking of water over a longer period of time might cause this.

How much water do you have to drink for it to be a problem (water intoxication)?

Depends: It depends upon several things. If you are doing strenuous exercise or working in a hot environment then you will need more water. For most people drinking 6-8 8oz glasses of water a day is plenty. If you drink excessive water your kidneys can not process it and electrolytes get out of balance. This can be serious and cause the heart to get out of rhythm.

How much water can an 8 month old drink safely/daily without worrying about water intoxication?

How much water can an 8 month old drink safely/daily without worrying about water intoxication?

Less than 4 ounces.: I would not recommend no more than 2-4 oz of water per day for an infant that age. You would not need to worry about intoxication with volumes that small.

I drink 4-6 16.9oz bottles of water daily. Today I had 4 over the course of the day and then 2 within an hour. Could this cause water intoxication?

I drink 4-6 16.9oz bottles of water daily. Today I had 4 over the course of the day and then 2 within an hour. Could this cause water intoxication?

Unlikely: Depending on how many ks you weigh, drinking that much water shouldn't cause you any problems. A normal 70kg individual requires about 1600mL of fluid replenishment by natural losses daily. For heat, sweat, or other losses you would increase accordingly. For every 1 degree above 98 degrees Fahrenheit your daily fluid requirement increases by 125mL/day as well. Many gallons will cause trouble.

Fluids: There is nothing wrong with drinking fluids. With normal kidney function you should be fine. Drinking just before sleep may not be a good idea as you will have a very full bladder and may have to get up in the middle of the night

Is it possible to suffer from water intoxication drinking about 3 to 4 liters after a heavy meal?

No: Usually seen in psychiatric disorders, water intoxication occurs causing a low sodium level, with generally 15 to 20 liters intake. The kidney can dilute the urine and get rid of water quite well unless it is overwhelmed with that amount. The sudden lowering of sodium can cause serious neurological problems.

I have to run to the bathroom every 15 min. I have been drinking a lot of water lately. I'm just nervous that it's a sign of water intoxication.

Stomach flu: The stomach flu is caused by a virus that attacks your gastrointestinal system. There is no cure for the stomach flu. The remedies are: good rest, plenty of fluids intake, plain food like crackers, cereal, toast and rice. Take NSAID over the counter and tincture of time. Good luck.

What is the amount of water inned to drink daily, because I drink liters of water daily and now I heared about water intoxication, what is it and how should I control my water consumption?

WHY?: Why drink so much water? Water intoxication is real but rare. There is a silly urban legend about 8 glasses of water a day. Never made sense. Ignore it. Drink "liters"??? If this is OCD look for cognitive behavior therapy from a psychologist. If you have urinary stones, consult a nephrologist.

I drink one or two litres of water an hour before sleep. Will this give me water intoxication, killing me in my sleep?

I drink one or two litres of water an hour before sleep. Will this give me water intoxication, killing me in my sleep?

No: However, most doctors would recommend drinking less water closer to bedtime for a variety of reasons. I would change the interval to 2 hours before bedtime and make sure to go (void) before going to sleep.

During colonoscopy prep, how can you drink so much fluid during such a short period of time and not suffer from water intoxication?

Drink slowly: Drink slowly the liquid as tolerated. Some preparations are "low volume" (2 liters or less) and easier to tolerate, and may be the preferred prep if you are concerned about getting full. You will not get intoxicated with water!

From a week I had water intoxication from drinking 8 litres I vomited twice. I made a CT and soduim its normal but the headache continual till now?

From a week I had water intoxication from drinking 8 litres I vomited twice. I made a CT and soduim its normal but the headache continual till now?

See neurologists if: Headaches persist. You do not give the cause of the water intoxication, and how severe it was. It may take a long time before your sodium levels are back to normal, and headache may persist for some time. If it has been a week or more since the correction of your electrolytes and you still have headache, talk to your pcp or ask to see a neurologist.
