You are correct, Somatuline or Lanreotide can produce gall stones among other side effects. How long were you taking this drug before your gall bladder acted up? I am just short of 2 years. Something that might help with symptoms..........maybe some contributors.........
the “no-nos” added by lanreotide are spicy foods, tomatoes, fatty meats, cruciferous vegetables, sugar/sweets. No uncooked veggies, all should be well cooked.

Apparently, 1 person every 90 minutes in the U.K. is diagnosed with NETs, which might help promote research.
