Partial Antrectomy or Subtotal Gastrectomy

Care After

Refer to this sheet in the next few weeks. These discharge instructions provide you with general information on caring for yourself after you leave the hospital. Your caregiver may also give you specific instructions. Your treatment has been planned according to the most current medical practices available, but unavoidable complications sometimes occur. If you have any problems or questions after discharge, please call your caregiver. Recovery from antrectomy, partial, or subtotal gastrectomy can take up to 8 weeks or more. Allow time to heal and pay close attention to your diet during recovery. Most patients adjust well over time.


Everyone recovers at a different pace. Proper self-care will help you to recover fully and return to your normal activities.

  • Follow your caregiver's instructions.

  • Rest often, but try to move about each day.

  • Gradually add light activity to your daily routine.

  • Take pain or other medicines as directed. Do not drive if you are taking narcotics for pain.

  • Keep the incision area(s) clean, dry, and protected. Follow your caregiver's instructions for incision care and changing your bandages (dressings).

  • Follow up with your caregiver as directed. Regular blood tests to check for vitamin deficiencies and vitamin B injections are sometimes necessary.

  • You may develop a scar(s) at the incision site(s). Follow your caregiver's instructions for scar care after the incision area has healed.

  • You may gradually resume most activities, including sexual activity, as directed.

  • Menstrual cycles are commonly disrupted after surgery. You may be off schedule for up to a year.

  • Always discuss your medicines with your caregiver before taking them.

  • If you smoke, quit. Smoking slows the healing process.

Special diet instructions:

  • Eat small amounts of food throughout the day instead of large meals. If too much food moves quickly through your system, this can lead to "dumping syndrome" (cramps, nausea, dizziness, discomfort).

  • Your caregiver will help you understand the best foods to eat to prevent complications. Eat foods high in calcium, iron, vitamin C, and vitamin D.
