📋 Quick Navigation
The second trimester is often called the "honeymoon phase" of pregnancy. However, upper abdominal pain during pregnancy can still occur and cause worry. Understanding the causes of abdominal pain in pregnancy helps you know when it's normal and when to seek help.
This article focuses on stomach pain in pregnancy during weeks 13 to 27, explaining typical reasons, warning signs, and safe ways to find relief.
Common Causes of Upper Stomach Pain in the Second Trimester
1. Growing Uterus & Fetal Pressure
The expanding uterus pushes upward on the stomach, ribs, and diaphragm, causing stretching or mild pain under the ribs.
Location: Under ribs, sides | Relief: Rest, warm compress, posture support
2. Heartburn & Acid Reflux
The uterus presses on the stomach, pushing acid upward and causing a burning sensation in the chest or upper abdomen.
Location: Upper chest/belly | Relief: Small meals, stay upright, elevate head
3. Gas, Bloating & Indigestion
Slower digestion traps gas, leading to sharp or cramping feelings in the upper belly.
Location: Upper/mid abdomen | Relief: Walk, fiber intake, hydration
4. Constipation
Hard stools and straining can contribute to overall abdominal discomfort that radiates upward.
Location: General abdomen | Relief: High-fiber diet, plenty of fluids
⚠️ Less Common Causes
Gallstones, liver issues, or rare complications like preeclampsia can also cause upper abdominal pain. Most everyday pain stems from benign causes listed above.
Differentiating Normal Discomfort from Concerning Pain
✅ Normal Upper Abdominal Pain
