Gallstones are hardened bile deposits in the gallbladder that can cause symptoms like abdominal pain, nausea, and vomiting. While some people experience no symptoms, others may need treatment. Dr. Abhinandan Jadhav at Sapphire Superspeciality Clinic in Nashik highlights key causes of gallstones, including blood sugar imbalance, estrogen dominance, food allergies, chronic stress, low-fiber diets, leaky gut syndrome, obesity, rapid weight loss, low stomach acid, and cholesterol-lowering medications. Understanding these factors is essential for prevention and early treatment.
