Can I still get pregnant after bariatric surgery?

Obesity can make it difficult for some women to become pregnant, so bariatric surgery can actually help with fertility.

If you want to become pregnant, you should wait until your weight stabilizes — about 18 to 24 months following surgery — because rapid weight loss and nutrition deficiencies can harm a developing fetus.

The most common problem-foods include:

Excess skin after losing weight — what can I do about it?

If you're concerned about excess skin on your stomach or other areas, plastic surgery is an option.

After you're at a stable weight — about 12 to 18 months following surgery — you should meet with a plastic surgeon to discuss your options and insurance coverage.
