Will People Know I Had Weight-Loss Surgery?

Nobody can tell from looking at you that you had a gastric sleeve. What people may notice, how small the scars are, and how to decide who to tell and what to say.

In short

  • People cannot tell by looking at you that you had surgery. The scars are small and usually covered by clothes.
  • What people may notice is your weight loss, and that you eat smaller portions.
  • Who you tell is your choice. Telling at least one person close to you helps in the first weeks.

Weight-loss surgery still carries a stigma for some people. You may have heard comments like "that is the easy way out" or "why not just diet?". It is natural to wonder whether people will be able to tell, and what you will say if they ask.

Can anyone tell?

Usually not by looking at you. At 360 Sleeve, a gastric sleeve is done laparoscopically, through five small incisions on the belly, each about 5 to 15 mm long. They are similar to the incisions for a laparoscopic gallbladder removal. They usually heal into small scars that fade over time, and most clothing covers them.

What people may notice

  • Your weight loss, which is usually fastest in the first months.
  • Smaller portions, eating slowly, and not drinking with meals.
  • Saying no to some foods and drinks, such as pop or alcohol.
  • For some people, hair shedding a few months after surgery. It is common and usually temporary.

These changes can lead to questions. It helps to think about your answers ahead of time, so you can say as much or as little as you like.

Telling people is your choice

Your health is your own business. You do not owe anyone an explanation. Some people tell everyone, some tell a few close people, and some simply say they are working with a medical team on their health.

  • At work, you can say you are having a planned medical procedure and need time off. Most people take 1 to 3 weeks off, depending on their job.
  • At meals, "I am full, thanks" or "I eat smaller portions these days" is enough.
  • If someone makes a hurtful comment, you can end the conversation. You do not need to defend your choice.

Who should know

We suggest telling at least one person close to you, such as a partner, a family member or a friend. Someone needs to drive you home on the day of surgery and stay with you the first night, and a little help in the first days makes recovery easier.

The people you live with will also notice the changes in your meals. Their support at home helps a lot.

If you feel judged

Choosing surgery is a medical decision about a chronic condition, made with a medical team. Canadian obesity guidelines describe weight bias and stigma as harmful to health, and work to reduce them. There is nothing to be ashamed of in getting treatment.

If comments are getting to you, talk to people who understand. 360 Community connects you with others who have had surgery, and your care team is there for you too.
