Why does my stomach hurt when I sit down but not when I stand up?

Abdominal pain refers to pain in the belly. In general, abdominal pain that occurs when sitting but subsides upon standing may be caused by poor sitting posture, indigestion, gastritis, gastroesophageal reflux disease (GERD), pelvic inflammatory disease, or other conditions. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analysis is as follows:

1. Poor Sitting Posture

When sitting, changes in body weight distribution can compress the abdominal muscles and cause pain. Adjusting incorrect sitting posture may effectively alleviate symptoms.

2. Indigestion

Indigestion may lead to bloating, discomfort, and abdominal pain. These symptoms are often more noticeable after eating or while sitting, as food and gas accumulate in the abdomen. Symptoms may ease upon standing. It is recommended to follow medical advice and use medications such as Baohe Pills or Jianwei Xiaoshi Tablets to relieve symptoms.

3. Gastritis

Gastritis involves erosion of the stomach lining. When sitting, pressure on the eroded areas may trigger abdominal pain, leading to the aforementioned symptoms. Patients are advised to follow medical guidance and take medications such as pantoprazole sodium enteric-coated tablets or ranitidine hydrochloride capsules for treatment.

4. Gastroesophageal Reflux Disease (GERD)

GERD refers to the backflow of stomach acid into the esophagus, usually accompanied by pain and discomfort. Symptoms may worsen when sitting, as body position can facilitate the reflux of acid into the esophagus. Upon standing, acid reflux may decrease and pain may subside. Medications such as lansoprazole tablets or omeprazole enteric-coated tablets may be used under medical supervision to relieve symptoms.

5. Pelvic Inflammatory Disease

If a patient has pelvic inflammatory disease, abdominal pain may occur when sitting. It is recommended to follow medical advice and use medications such as metronidazole tablets or Fuke Qianjin Tablets for treatment.

If symptoms are severe, patients should seek timely medical care to avoid delays in diagnosis and treatment.
