Gastric Bypass Surgery FAQs

How quickly will I lose weight after my gastric bypass?

The rate of weight loss after a gastric bypass varies from person to person based on many different factors. However, generally, it is estimated that you can expect to lose up to 60% of your excess weight in the first two years after having a gastric bypass. A lot of weight loss is often seen in the first six months after surgery but some people find that their weight plateaus after this. As with anyone trying to lose weight, it depends on how much you eat and what exercise you do.

Do I need a GP referral to have gastric bypass surgery?

The majority of surgeons will be more than happy to see you for an initial consultation without a GP referral. However, they may wish to contact your GP if you do decide to go ahead with the gastric bypass procedure. This will be to gain more information about your medical background.

How do I know if I am suitable for a gastric bypass?

This will depend on a number of factors. These include your BMI, your age, your current medical and psychological health, and your motivation to go ahead with the surgery. The final decision on your suitability for a gastric bypass will be made by your surgeon but they will of course involve you in the decision-making process.

Will having a gastric bypass affect my ability to get pregnant?

A gastric bypass should have a positive impact on pregnancy and childbirth. Many women with obesity suffer from subfertility as a result of their weight. However, as you lose weight, your fertility increases and you are much more likely to be able to conceive. It is important that you are aware of this effect if you want to avoid getting pregnant.

Additionally, losing weight will result in a significant reduction in the risk of complications during pregnancy and childbirth. Your weight loss will allow you to be much more active both during and after pregnancy. This will ensure that you can get maximum enjoyment out of what should be a very happy time in your life.

Will I have excess skin folds if I lose weight?

Losing a lot of weight can result in the overlying skin becoming excessive and sagging as a result. The more gradual and controlled the weight loss is, the less likely this is to happen. However, if you have a high BMI and are successful in reducing this significantly, then you may find that you do have excess areas of skin. This particularly occurs around the breasts, abdomen and limbs. This is not harmful and some people have no problems. However, if you do suffer distress due to the excess skin then this can be surgically treated. This is a cosmetic treatment and something that can be discussed in greater detail with your surgeon.
