3 weeks after Vanquish treatment, have extreme diarrhea pain in lower abdomen and bad indigestion. Is this normal?

I strongly fee that your symptoms are completely unrelated.  Vanquish does not make parients feel sick like you describe.  The only side effects we have experienced in our office is muscle sorenness, like when you work out too hard, and occasional swelling as well as nodules.  Those symptoms resolve themselves usually within the week.

It is unlikely due to your Vanquish treatment. If it persists, I recommend following up again with your Doctor. Keep in mind, Vanquish needs a combination approach to get the most improvement. I recommend combining Vanquish with Venus Legacy/Exilis Ultra treatments. We currently use a fire and ice treatment with Coolsculpting and Vanquish for good results in fat removal. However, a VASER hi definition procedure would give you the best results for body shaping, but requires more down-time. See an expert for a formal evaluation. Best, Dr. Emer

It's very unlikely for Vanquish to be causing indigestion or diarrhea.  Patients do routinely report more regularity in their bowel movements while undergoing Vanquish treatments, perhaps in part because we ask patients to hydrate better.  Vanquish can sometimes cause nodules to form under the skin which resolve with time and represent areas of fat necrosis.  Combining with Zwave helps move more fat out of the area as well.

Thank you for your question and sorry to hear of the problems you are experiencing. I believe it is highly unlikely that your problems relate to your Vanquish treatments. By the description of your complaints you have some form of inflammatory condition, bacterial overgrowth of the gut or malabsorption. With 3 weeks duration, you should seek referral to a gastroenterologist for a thorough workup of your problem.I hope this was helpful - Dr. Moore.
