Hi there.
Your problem seems to be related to the gastrointestinal region rather than the shoulder surgery per se.
Either you are having some sort of medication which is killing your hunger or you had some medication in the past which has caused damage to your stomach/intestinal lining.
If you are on some medication then get it changed by your doctor.
If not then kindly consult a gastrophysician.
Tablet Cypon two tabs three times daily....half an hour before your meal time wll enhance your hunger.
Also take some regular antacid like tablet sompraz (esmoprazole) 40 mg daily.
Good luck.

Hi, Welcome to HCM forum. The aim of a Bankart repair operation is to restore stability to the shoulder. The operation is suitable for people who have detached the labrum and ligaments at the front of the shoulder as a result of a violent dislocation. Your arm is placed into a special shoulder-immobilising sling and exercises and physiotherapy start on the day of surgery. Your physiotherapist will teach you all you need to know for the first couple of weeks before your discharge from hospital. sling will be retained for a period of four weeks during which time you will be quite one-handed. At four weeks the sling generally goes and increased exercises and movement are encouraged. Remember any surgical intervention in any part of body needs time to heal. Shoulder joint is is most commonly used in our daily routine activities, so it takes more time to heal. Physiotherapy and exercises continue for four to six months and this can also cause u pain. In addition to regular treatment with the physiotherapist, follow up is required with your surgeon. This is to monitor and guide progress and to look out for complications. Dont worry u will recover and your pain will come down in 2-3 months. Regards
