A study conducted on 88,795 patients found that 13.9% reported bloating in the last week. Out of the participants who had reported bloating, 58.5% never sought medical help and 29% of them reported using self-managing their bloating or not comfortable sharing symptoms with their healthcare providers.

  •  Consuming high-fiber foods like lentils, beans, and veggies like cabbage and Brussels sprouts
  •  Sugar and lactose intolerance
  •  Bacterial overgrowth
  •  Constipation
  •  Aerophagia (swallowed air) due to fast eating, smoking, drinking carbonated beverages, and chewing gum

How Much Weight Can You Gain From Bloating?

The amount of weight gained due to bloating varies from person to person. Bloating typically leads to a temporary increase in weight due to the accumulation of gas or fluid in the digestive system. This can, at most, result in a few pounds of weight gain. However, this is not the weight of actual fat or muscle. An individual’s body weight returns to normal once the bloating is relieved through natural remedies or medical treatment. But if you experience persistent or unexplained weight changes, consult a healthcare professional to rule out any underlying health issue.

In most cases, the symptoms of abdominal bloating can be minimized or prevented by changing your lifestyle habits. Here are a few tips.

Warning Signs You Should Not Ignore In Case Of Serious Bloating

Consult a doctor immediately in case you experience severe bloating and the following symptoms:

  •  Weight Loss

If you notice sudden weight loss and bloating without dietary changes and exercising, consult a doctor. It could be due to tumors or overgrowth that press on the intestines, making you feel bloated or full after just a small amount of food.

Ascites refer to a condition that causes fluid buildup in the abdominal cavity or pelvis area and causes bloating and weight gain. Ascites may indicate serious complications like liver disease, kidney failure, and cancer (4).
