Abdominal Bloating

Abdominal Bloating min

Human gut produces gas during the digestion process of food. This gas is collected in the stomach and intestines and leads to abdominal bloating. Some people are more sensitive to this gas and suffer from abdominal pain, heavy belching or fart excessively. The primary reasons for this condition can be mainly due to choices of diet that produce more gas, swallowing of air while chewing food, bowel diseases or lifestyle issues. The remedies are through making changes to the diet and consuming antacids and digestive aids after every meal.

Diagnosis

Bowels or abdomen contain gas which is a result of the digestion process. Some of the air which enters the abdomen while chewing food or drinking is also present. Large amounts of air is swallowed (aerophagia) when one eats fast or hurriedly gulps down a drink, which makes its way into the gullet or the esophagus. Most of the air escapes when we belch or burp after a meal. The air that is unable to pass through belches results in bloating and causes a hard and swollen belly. The swallowed air along with the gases released from digestion of food passes through the anus in the form of passing wind or flatulence.

Foods like broccoli, baked beans and brussels sprouts are known to cause gas when eaten in above average quantities. This gas is mainly composed of carbon dioxide, hydrogen, methane and contains traces of sulphur- which gives a bad odour to the farts. Gases are also produced due to bacteria which reside in our gut and help in digestion of food. Abdominal bloating can be very uncomfortable when the stomach is blown out and is tight due to gas formation within. This can also cause cramps and pains in the abdomen.

Symptoms of Bloating

Excessive and repeated burping or farting is a sign of gas-related bloating of the abdomen. When the gas settles in the large intestine under the liver or spleen, it leads to cramps and pain. A bloated belly causes discomfort and usually subsides on its own in a few hours.

People suffering from ailments like irritable bowel syndrome or gluten intolerance produce more than average amounts of gas during the digestion process. Irritable bowel syndrome is a common condition where bouts of abdominal pain are linked to changes in bowel habit like constipation or diarrhea.

Causes

Foods that cause excessive wind in the abdomen are,

  • Broccoli & Brussels sprouts
  • Starchy foods such as potatoes, corn and noodles

  • Side effect of Medicines- Excessive gas or bloating can be side-effects of common medicines like metformin (for diabetes) and lactulose (laxative). Antacids like magnesium trisilicate should be taken along with medicines to aid digestion and reduce gas.
  • Bloating as a symptom of diseases- Few diseases of the bowel like acute gastroenteritis (tummy bug) is caused by infection of the stomach and results in increased gas formation and bloating of abdomen. Long term diseases like Coeliac disease (gluten intolerance), Inflammatory bowel diseases (Ulcerative colitis in large intestine, Crohn’s disease or inflamed gut) cause abdominal bloating frequently in the patients.

Other medical conditions that cause bloating are,

  • Diverticulitis- infection of large intestine
