Gastrointestinal Side Effects. Using turmeric in your cooking is considered safe and unlikely to cause side effects. Taking large doses of the spice or of supplements can result in gastrointestinal side effects. The most common gastrointestinal side effects are stomachache, gas, nausea and indigestion. Talk to your doctor and reduce the amount of turmeric you're taking if you experience any of these side effects.
Your stomach is an acidic environment with a low pH of between 1 and 3. Parietal cells in the wall of the stomach secrete hydrochloric acid (HCl). If your esophageal sphincter; basically the lid to your stomach; isnât closed properly, HCl will creep into your esophagus resulting in heartburn.
1 Specialized exocrine cells of the mucosa known as mucous cells secrete mucus into the lumen of the stomach and into the gastric pits. 2  This mucus spreads across the surface of the mucosa to coat the lining of the stomach with a thick, acid-and enzyme-resistant barrier.
