For chronic gas, over-the-counter simethicone can help relieve bloating and pressure. If your abdominal pain is related to muscle spasms in the gut, a doctor may prescribe antispasmodics like dicyclomine. Probiotics can also support overall gut health. However, because your symptoms are chronic, it is very important to consult a healthcare provider for a proper evaluation to find the root cause, such as irritable bowel syndrome (IBS) or dietary sensitivities, rather than relying on self-medication. Please seek immediate medical care if you experience severe pain, fever, blood in your stool, or unexplained weight loss.
