Full Answer

Irritable bowel syndrome is an acute condition that affects the colon and causes symptoms such as cramping, bloating, constipation and diarrhea. Gallstones are deposits that are in the gallbladder. These stones block the bile ducts. Apart from causing a swollen stomach, gallstones cause itchy skin, fever, abdominal pain and jaundice, as claimed by Healthline.

Lactose intolerance is when the small intestine cannot break down lactose, as stated by Healthline. This condition can lead to many gastrointestinal problems. Ascites is a condition whereby fluid fills the space between organs and the abdomen. It commonly causes nausea and abdominal bloating.

Typical symptoms of a swollen stomach include vomiting, fever, abdominal pain, diarrhea and belching as reported by MedicineNet. Treatments depend on the cause of a swollen stomach. For symptoms due to digestion issues, avoiding constipation is advised. Eating food that is rich in fiber, such as veggies, whole grains, nuts, legumes and fruits, reduces constipation, as does drinking plenty of water. Eating quickly and not chewing food properly can contribute to bloating, notes WebMD.
