Since most cases of constipation are temporary, simple lifestyle changes, such as getting more exercise and increasing ones intake of fiber, can contribute to alleviating constipation. Some cases of constipation will continue to worsen and require unconventional methods to release the feces and reduce the amount of stomach bloating. Blood in the stool, intense pain in the abdomen, rectal pain, unexplained weight loss, and continued bloating and constipation not relieved by the above lifestyle changes should be reported to a doctor. Bloating consistently accompanies constipation, and they will not develop without an underlying cause. Heartburn and acid reflux
Painful burning sensations in the chest that are caused by gastroesophageal reflux is known as heartburn. Reflux is the backflow of gastric acid juices from the stomach into the oesophagus. Heartburn has different triggers, including certain foods, medications, obesity, and stress. These triggers are different for each individual. Gastroesophageal reflux disease or GERD is a chronic condition that can lead to more serious complications like esophageal cancer. Treatment options are available to treat the symptoms and the condition, but there is no cure for the disease. Symptoms include burping, abdominal and stomach bloating, along with pain and discomfort. Heavy meals, lying down or bending over after eating should be avoided to help prevent reflux from occurring. The stomach bloating experienced with reflux is intense and will remain until the food is digested all the way.
Medications
There are many over-the-counter (OTC) medications that can be used to treat bloating. Food enzymes can be found in some products that will help break down the sugars found in grains, vegetables and dairy products. They can be taken before food is consumed or added to the food that causes the gas and bloating. The most common treatment is antacids. These medications have no effect on the gas that is present in the intestines but enable gas build-up to be belched away more easily, reducing the amount of bloating that develops. Another treatment is simethicone, an oral anti-foaming agent that helps the body to expel the gas more quickly. Combinations of prokinetics, such as domperidone + metoclopramide + diphenhydramine (the latter for the prevention of extrapyramidal reactions, especially acute dystonic reactions) + proton pump inhibitors (PPIs), have dramatic effects on bloaters and belchers especially.
