Drinking too much water might cause gastrointestinal irritation and other symptoms.  It’s a little worrying if your stomach hurts after drinking water. Isn’t water, after all, healthy for you? Too much water, like too much of anything else in life, can be harmful. Overhydration can lead to a variety of issues, including stomach irritability.

Yes, excessive water consumption can irritate the stomach and cause other problems. Consult a doctor if you have stomach pains after drinking water on a daily basis.

Stomach pains after consuming water

Do you get stomach pain after you drink water? There is still food in your stomach if you drink water after your meal. As part of the digestive process, the water fills your stomach even more, increasing pressure and triggering the formation of more stomach acid. Heartburn may occur as a result of this. When the stomach’s volume expands, whether from food or fluids, the stomach begins to produce acid to facilitate digestion.

Water has a considerably faster rate of gastric emptying than solid food since it contains no nutritious components to break down for digestion. While this means that any discomfort induced by drinking water should be temporary, it’s worth noting that gastric emptying differs from one person to another.

Gender, menstrual status, and smoking status all affect solid gastric emptying, according to a study published in the Journal of Neurogastroenterology and Motility in July 2014. Men who smoked emptied their bladders faster than nonsmokers, and men in general emptied their bladders faster than women. Women who were in the luteal phase of menstruation emptied their uteruses more slowly than those who were in the follicular or menopausal periods. Gastric emptying rate was unaffected by age, BMI, or alcohol use.

Recommended water intake

While there are no recommendations for how much plain water people should drink every day, the Centers for Disease Control and Prevention (CDC) claim there are recommendations for daily total water intake. Water absorbed from food, drinking water, and other liquids is referred to as daily fluid intake. The amount depends on a number of circumstances, including age, gender, pregnancy, and nursing.

According to the National Academies of Sciences, Engineering, and Medicine, a sufficient daily fluid consumption for a healthy adult living in a warm environment is 11.5 cups (2.7 liters) for women and 15.5 cups (3.7 liters) for men, with food accounting for around 20% of the daily fluid intake.

Drinking too much water all at once might also induce stomach ache. It’s tempting to drink a lot in one session if you’re behind on your daily intake. You should be aware, however, that drinking so much water at once carries some hazards.

Dangers of Excessive Water Consumption

Water intoxication, also known as hyponatremia, can occur when you drink too much water. Hyponatremia occurs when the body’s sodium levels are excessively low, according to the Merck Manual. The extra fluid must be absorbed by the cells, causing them to expand. In moderate situations, the swelling might produce confusion and weariness. Seizures, coma, or death may occur in more serious cases.

Drink little amounts of water throughout the day and only when thirsty to avoid water intoxication. Every hour, the human body can only process a specific amount of water. According to the National Kidney Foundation, drinking more than the body can tolerate can lead to a variety of issues, particularly in people who have kidney disease.

Possible reason for stomach pains after drinking water

It’s not uncommon to experience acidity in the stomach after drinking water, which is the core cause of the majority of the ailments you may be experiencing. However, just because something happens frequently does not mean you have to accept it and let it annoy you.

You should try to pinpoint what is causing your burning stomach sensation in order to determine the best therapy option. Here are a few possibilities for what’s causing this issue. If you suspect one of these conditions is affecting you, talk to your doctor for more information as well as ideas on how to cope with it at home.

Ulcerative colitis

Ulcers in the stomach can develop for a variety of reasons. They are frequently associated with stress, yet this isn’t the primary cause. If you have a stomach ulcer, it’s likely that the burning sensation you’re experiencing when you drink water is due to it. Acidity can be created by water, which aggravates the ulcer and makes it ache and burn. If you do have a stomach ulcer, your doctor will prescribe medication to help you get rid of it. The removal of severe stomach ulcers may necessitate surgery, but not all of them do.


Gastroesophageal reflux disease (GERD) is also known as acid indigestion or reflux. The lower region of your esophagus is affected when you have this illness. When you have GERD, this section of your esophagus opens up more than it should, allowing acid from your stomach to rise higher than it should. This acid burns your esophageal lining, which can lead to cancer or other problems in this area of your body. If you have this condition, drinking water might make it worse by causing the stomach to create more acid.


There are a variety of reasons why you could experience inflammation in your digestive system, ranging from the relatively common stomach illness to the serious Crohn’s disease, and everything in between. If you’re experiencing this, drinking cold water may help you relax, however drinking hot water may induce a burning feeling. Even cold water might aggravate the burning and agony of an inflamed stomach lining in certain persons with extremely sensitive digestive systems.

Irritable bowel syndrome

This illness causes inflammation in both the intestines and the stomach, and it frequently occurs in conjunction with ulcers and GERD. IBS can be controlled with diet, exercise, and, in certain cases, stress management. However, if you have IBS and are experiencing a particularly terrible episode, drinking water is likely to induce discomfort in your stomach or intestines, as well as heartburn. When you have IBS, it’s critical to drink water slowly and at room temperature, since this will help it go down easier.

Stomach aches from contaminated water

Yes, the quantity of water you consume is an important factor. However, water quality is also a significant consideration. If you have stomach aches, the source of your problem could very likely be the quality of your drinking water.

Drinking sterilized tap or well water can give you a stomach ache. Viral gastroenteritis, an inflammation of the stomach, small and large intestines, may be caused by untreated water. A variety of viruses can produce stomach aches, vomiting, and diarrhea as a result of this infection. Bacteria in the water, such as Salmonella and E. Coli, can induce the same symptoms. In most underdeveloped nations, the link between these microbial pollutants in drinking water and stomach pain is quite significant and a big problem.

Arsenic is another dangerous water contaminant that can induce stomach pains. Arsenic is a chemical element that is found in nature and can be found in the soil. Arsenic poisoning can cause headaches, stomach aches, convulsions, diarrhea, vomiting, and even death in some people. While the EPA regulates arsenic levels in drinking water in most nations, there is no way of knowing how much arsenic is present in many water sources unless they are tested on a regular basis. A reverse osmosis water filtering system is the most effective approach to remove arsenic from water.

Allergic reactions to chemicals put into the water by your municipality might also cause stomach problems. To protect against bacterial contamination, most cities and municipalities around the country will add abrasive chemicals like chlorine and chloramines to the water. The harmful chemical fluoride, which is frequently added to tap water, is of special concern. Fluoride has some advantages in terms of preventing cavities, but it is extremely deadly at greater concentrations. Drinking fluoridated water at even the low levels set by their towns, which are generally safe, has caused stomach problems in certain persons who are particularly sensitive. Because fluoride is known to be highly hazardous, many people think that no amount of fluoride should ever be consumed by drinking water.

Those who suffer from stomach problems on a daily basis should have their water checked for toxins. If contamination is found to be the problem, a reverse osmosis water purifier should be installed. Reverse osmosis systems can remove 90-99% of impurities such as arsenic, fluoride, and microorganisms that can cause stomach discomfort.


What to do once I start feeling sick after consuming too much water?

Your body’s way of getting rid of a toxin is to vomit. Let’s say alcohol.  Rather than trying to stop yourself from puking, focus on making yourself feel better until your body has completely eliminated the alcohol.

Here are a few suggestions for reducing nausea and vomiting side effects:

  • Rehydrate yourself by sipping modest amounts of clear drinks. Wait until you’ve had a chance to recover for roughly 30 minutes. Water, Pedialyte, Gatorade, or Powerade are all examples of transparent liquid. It also works with low-sugar ginger ale.
  • Rest as much as you can. On the day of a hangover, avoid overindulging.  You can feel better by sleeping it off.
  • Don’t drink again the night after a vomiting incident to give your stomach and body a break.
  • Ibuprofen is an anti-inflammatory medication that can help you feel better. The liver breaks down acetaminophen, and the liver is already busy taking down extra alcohol by-products, therefore most doctors recommend ibuprofen over acetaminophen. Ibuprofen, on the other hand, can irritate some people’s stomachs, so take it with small amounts of food.
  • Keep your energy levels up by eating little amounts of bland meals like toast, crackers, or applesauce. Wait a few minutes after you’ve vomited again to avoid triggering the vomiting reflex.

Is it safe for me to drink water from the tap?

With so much advertising for bottled water and water filtration systems, it’s reasonable if you’re wary of the water coming out of your kitchen faucet. Although some cities’ water contains trace amounts of pollution, most healthy adults may still drink from the tap in most areas—and tap water is still the most cost-effective and easiest option to stay hydrated.

Trendy bottled water brands continue to dominate supermarket shelves, but the environmental impact of all that plastic is considerable: Apart from the large quantity of fossil fuels and greenhouse gas emissions required to power manufacture and shipping, the vast majority of plastic bottles end up in landfills rather than recycling bins. Because of these factors, many individuals prefer tap water.

While tap water quality varies by place, there are certain fundamental concepts that apply in most cases, as well as location-specific resources to help you decide whether tap water is good for you.

Final thoughts

Truthfully, there are a few things to consider while trying to figure out what’s causing your stomach to burn after drinking water. Only a doctor can tell you for sure what’s causing the problem, but it’s always a good idea to have some information so you can discuss your worries with your doctor. And, in some cases, these issues can be readily managed with over-the-counter medications, so you may never need to see a doctor unless the irritation persists.
