Over 11,000 people need to hear this doctor's warning. Proton pump inhibitors are India's most over-used drug class. Dr. Anand Karnam explains why taking them for every digestive complaint causes serious long-term damage.
Key Points
- Proton pump inhibitors (PPIs) like omeprazole are among the most overused medications in India — taken for months or years without medical supervision.
- Long-term PPI use causes B12 deficiency, magnesium deficiency, and calcium malabsorption — all of which damage the nervous system.
- B12 deficiency from PPIs causes peripheral neuropathy, cognitive decline, and fatigue that patients never connect to their 'gas tablet'.
- PPIs increase risk of Clostridium difficile gut infection by eliminating the acid barrier against gut pathogens.
- Most acid reflux can be managed with lifestyle changes — weight loss, small meals, no late eating, head-of-bed elevation.

"In India, omeprazole is taken like a vitamin — 'just for gas'. But proton pump inhibitors are powerful acid suppressants with serious long-term neurological effects. I routinely find severe B12 deficiency in patients who have been on PPIs for years, causing tingling, fatigue, and cognitive fog they never connected to their gas tablet. If you have been on a PPI for more than 3 months without a clear diagnosis, ask your doctor if you genuinely still need it."
Proton pump inhibitors — sold under names like omeprazole, pantoprazole, rabeprazole, and in combination as "DSR" tablets — are among the most widely prescribed and self-medicated drugs in India. They are taken for acidity, gas, heartburn, gastric discomfort, and routinely co-prescribed with every NSAID or antibiotic. Many people take them daily for years without any review. This is a serious problem.
What PPIs Do
Proton pump inhibitors permanently inhibit the proton pumps in the stomach lining — reducing acid production by up to 95%. For genuinely acid-related conditions (GERD, peptic ulcer, H. pylori eradication), they are essential and life-changing medications. The problem is their widespread use for conditions that do not involve excess acid — including functional dyspepsia, bloating, stress, and IBS — and their use without a time limit.
Long-Term Side Effects
Kidney damage: Multiple large studies have shown PPIs increase the risk of chronic kidney disease by 20–50% with long-term use. The mechanism involves interstitial nephritis — an inflammatory process in the kidney tubules.
Bone fractures: Stomach acid is required to absorb calcium. Long-term PPI use reduces calcium absorption → bone density loss → increased risk of hip, wrist, and spine fractures. Risk increases significantly after 1 year of continuous use.
Magnesium deficiency: PPIs impair magnesium absorption → low magnesium → muscle cramps, heart arrhythmias, and neurological symptoms.
Vitamin B12 deficiency: Stomach acid releases B12 from food. Long-term PPI use → B12 deficiency → peripheral neuropathy, anaemia, and cognitive decline.
Increased infection risk: Stomach acid is the first line of defence against swallowed bacteria. PPIs reduce this barrier → increased risk of C. difficile (severe diarrhoea), pneumonia, and gut infections.
Cognitive effects: Some studies suggest long-term PPI use is associated with increased dementia risk — potentially related to B12 deficiency and magnesium deficiency affecting brain function.
The Right Approach
PPIs are appropriate for: GERD with confirmed oesophagitis, peptic ulcer disease, H. pylori eradication, prevention of NSAID-induced ulcers (during NSAID use only). They should be used at the lowest effective dose for the shortest necessary duration. They should NOT be taken preventively "for gas" without a diagnosis.
