Traveller’s diarrhoea: It is an intestinal infection in which there is the passage of unformed stools due to eating or drinking contaminated food or water while travelling. Symptoms include nausea, vomiting, bloating, fever, gas, loss of appetite, and the urgent need to poop.

The liver cannot remove toxins from the body adequately, which results in a buildup of toxins in the blood, thereby leads to brain damage. Symptoms include confusion, forgetfulness, difficulty thinking, low concentration, personality changes, and problems with small hand movements.

Irritable bowel syndrome (IBS): It is a condition which affects the large intestine. Symptoms include abdominal pain, cramps, gas, constipation, and diarrhoea.
