Why do I have stomach fullness after taking pain medicines?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am 61 years old and have hypertension and diabetes, which were diagnosed recently. I have been experiencing stomach fullness for the past few days. I also have back pain. After taking some pain medications, I developed stomach fullness, bloating, and abdominal pain. There is no vomiting or loss of appetite, but I have chronic constipation.

A general physician has advised some medicines, including Enzigest, Nexpro, Normaxtin Trio, Boxibat, and Vibact. Kindly advise whether it is appropriate to continue these medicines or if I should consult a gastroenterologist for further review.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern.

The symptoms of stomach fullness, bloating, constipation, and abdominal discomfort that started after using pain medications are quite common. Many pain-relieving medicines can irritate the stomach lining and slow bowel movements, leading to these problems.

  • The medicines prescribed by the doctor are generally considered safe for short-term use.

  • Esomeprazole helps reduce stomach acid and protects the stomach lining.

  • Enzigest (digestive enzyme preparation) supports digestion and reduces heaviness after meals. Vibact (a probiotic containing beneficial gut bacteria such as lactic acid bacillus) helps restore healthy intestinal flora.

  • Normaxtin Trio (a combination laxative containing stool softener, fiber, and osmotic agent) helps relieve constipation and improve bowel movement.

  • Bixibat (a bile acid–related digestive aid) supports fat digestion and may reduce bloating.

Since diabetes mellitus, high blood pressure, and long-standing constipation are present, symptoms should be monitored closely. If abdominal pain increases or if vomiting, fever, blood in the stool, loss of appetite, or unexplained weight loss develops, consultation with a gastroenterologist is advised.

Even if symptoms improve, it is reasonable to consider an abdominal ultrasound and basic blood tests to rule out gallbladder, liver, or pancreatic conditions, especially since the digestive system reacted after medication use.

For now, the medicines may be continued as prescribed. Adequate water intake is recommended, dietary fiber should be increased gradually, and oily or spicy foods should be avoided until symptoms settle. If there is no improvement within one week or if symptoms worsen, a gastroenterology review is strongly recommended.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.

Thank you.
