thank your for posting query at HCM. You may eat crabs/shrimps. No harm but do NOT over eat and stomachfull. gall bladder is very important in the digestion process and diet modification maybe needed after gall bladder removal. Gall Bladder stores bile. Bile is very important and essential for digestion of Fats. when gall bladder is removed, fat digestion is IMPAIRED. a person without gall bladder, when eats a fat meal, its difficult to digest and feels very uncomfortable. therefore after removal of gall bladder, patients are adviced to: - avoid high fat meal and diet altogether - take nexium or Pantocid 20mg once daily before breakfast - small meals at regular interval is better - NOT eat stomach full. - not cold drinks and NO junk food - eat more fruits especially those rich in vitamin C (citrus fruits) if any further questions, feel free to ask. Health professionals aim to diagnose properly and manage patients according to their limited knowledge. Cure is blessed by the ONE who Created us, whose power and knowledge is unlimited . wish you good health. regards, Dr Tayyab Malik
