Is diarrhea a diet concern?

Diarrhea is a widespread condition, occurring several times each year in most people. This causes watery and loose stools, which increases the frequency of bowel movements. This will make the affected person feel weak and tired as the body has to lose a lot of fluids quickly, resulting in dehydration. Prolonged diarrhea is a dietary concern because it can lead to significant weight loss. It is normal for your weight to fluctuate slightly due to digestive issues. However, it does not indicate healthy weight loss.

How does Diarrhea cause weight loss?

Chronic diarrhea, which lasts for more than weeks, causes the body to lose a lot of fluids. The loss of body fluids can affect your weight. Other symptoms accompanying the condition, such as vomiting and loss of appetite, also make it difficult for the stomach to hold any food or liquid nutritional sources. These symptoms will reduce calorie intake, aiding in the process of involuntary weight loss. The rate of weight loss depends on how long and intense the diarrhea is. However, the weight loss due to diarrhea is primarily water weight. Once your bowel movements and appetite are restored, your weight will return to normal. Also, weight loss due to diarrhea depends on the type of condition you are affected by. It is of two types, acute and chronic diarrhea, each with a unique mechanism for weight loss.

acute diarrhea It usually affects a person for 24 to 48 hours, and the maximum volume and frequency of bowel movements can range from 5 to 7 times a day. This can cause a sudden energy flow due to a lack of nutritional absorption.

chronic diarrhea Can affect a person for several weeks, and the loss of nutrition will be for a longer period. A person may feel tired most of the time. The bowel movements range from 3 to 4 times per day.

And by the way, there is more information about diarrhea and weight loss. Here is a list of surprising health conditions directly or indirectly related to diarrhea that can lead to changes in weight.

sensitive gut disease

Irritable bowel syndrome is a common disorder that leads to persistent diarrhea or constipation. It is caused by a microbial imbalance of the gut and can cause symptoms such as gas, bloating, anemia and unexplained weight loss.

inflammatory bowel disease

Inflammatory bowel diseases such as Crohn’s disease and ulcerative colitis affect the digestive system and its normal function. As a result, it inhibits the absorption of nutrients, leading to anemia and weight loss.

celiac disease

Also known as gluten intolerance, celiac disease is an immune-mediated condition that induces an autoimmune reaction against gluten, a specific protein. As a result, it can cause severe damage to the intestinal walls, resulting in nutrient malabsorption, diarrhea, and weight loss.

chronic infection

Chronic exposure to contaminated water and food containing bacteria or parasites can lead to chronic microbial infections and persistent diarrhea. As a result, it damages the intestines, leading to malnutrition and unexpected weight loss.

malabsorption syndrome

In this condition, there is a deficiency of certain digestive enzymes in the body. As a result, it causes food to be absorbed and undigested. Also, over time, it can lead to weight loss due to malnutrition. Similarly, injury to the intestinal wall will block the absorption of nutrients, resulting in weight loss.

keto diet

High-fat and low-carb diets, known as keto, make it challenging for your body to process food. This will eventually result in diarrhea, affecting your weight and overall health.

lactose intolerance

Lactose is a sugar naturally present in milk and other dairy products. However, most people have lactose intolerance, the inability to digest lactose, which results in diarrhea after consuming dairy products. In addition, undigested lactose will cause an imbalance in the gut, leading to abdominal pain and short-term weight loss.

The HealthifyMe Note

Diarrhea leads to short-term weight loss, affecting your appetite or energy levels. And yes, in case you were wondering, diarrhea isn’t the solution to your weight concerns. The real weight loss journey is anything but fast and requires a balanced diet and proper exercise.

Tips to deal with weight loss due to diarrhea

Diarrhea lasting several days and up to a week can be severe and uncomfortable for your regular life. In addition, it will lead to unintentional weight loss. This can lead to various health problems including fatigue, malabsorption and nutritional deficiencies.

Here are some effective remedies to deal with diarrhea.

drink plenty of water

When your body becomes dehydrated due to diarrhea, it flushes out the remaining water from the muscles and internal organs, trying to compensate for the loss of water. So when you experience diarrhea it is necessary to consume plenty of water which also aids in weight management. However, avoid drinking too much water or other fluids.

Avoid consuming added sugar

When you are suffering from diarrhea, you should avoid consuming food with high sugar concentration. This includes soda, sports drinks and other carbonated drinks. Instead, if you want to maintain optimal weight, drink a healthy alternative such as plain water or unsweetened tea instead of sweetened beverages.

Increase intake of high fiber foods

Fibers play an important role in reducing the weight of a person without consuming unhealthy snacks. Plus, eating high-fiber foods is a great way to lose weight and manage diarrhea without relying on medications.

eat good fats

People suffering from diarrhea may crave high-fat foods due to the imbalance and improper functioning of their digestive system. To avoid the greater effects of stomach upset, try to include foods high in good fats such as nuts, seeds and avocados. These will help you gain extra energy to keep you active throughout the day.

The HealthifyMe Note

Weight loss due to irregular bowel movements is temporary, as it is simply a loss of water. So it will help if you don’t consider it an ideal way to lose a few kilos. However, adding more fiber to a weight loss diet will help with weight management and ensure regular bowel movements. If you’ve been experiencing diarrhea for a long time or are concerned with weight loss, it’s worth talking to your doctor.


Some people believe that diarrhea is a form of dieting. Even though it causes weight loss, diarrhea is not an ideal means of the process. Such a sudden unexplained loss of weight may indicate underlying health problems. Intentionally inducing diarrhea can lead to abdominal pain and digestive problems and even lead to a deterioration in overall health.

You will lose weight due to acute or chronic diarrhea, loss of body fluids, severe dehydration and decreased intestinal absorption of nutrients. Therefore, aim to lose weight only through diet and exercise, and not by affecting bowel movements. Simply put, a healthy weight loss journey should include a balanced diet, regular exercise and active lifestyle changes, improving overall health.
