Doctor insights & myth-busters
Myth: "Surgery should always be the last resort." Fact: delaying a genuinely needed operation (like an obstructed hernia or infected gallbladder) often makes it riskier — honest timing matters more than avoidance.
After gallbladder removal, most people return to a completely normal diet within weeks — start low-fat, then reintroduce foods gradually.
Black, tarry stools are never normal. They usually mean digested blood from the upper gut — get a gastroscopy without delay.
A 30-minute daily walk, weight control and not lying down for 2–3 hours after dinner prevent most reflux flare-ups.
