How Your Body Temperature Changes After Your Bariatric Surgery


Undergoing weight loss surgery means that your body and lifestyle are going to experience a number of changes. Some of the more expected changes can include weight loss, getting slimmer, and generally experiencing better health. There are others that are unexpected, but thankfully they’re manageable. Dr. Rosen and his entire bariatric surgery team in New York understand these issues, which is why we’re taking the time to cover one unexpected change: body temperature fluctuations.

Cold Intolerance

In general, some people just feel colder than others, and this doesn’t always directly relate to body weight. If you often feel colder than others and need a jacket or sweater, it’s possible that you have a condition known as cold intolerance. Cold intolerance has been linked to changes in body fat, resulting in issues regulating body heat.

Feeling Cold After Rapid Weight Loss

When your body loses weight rapidly as a result of bariatric surgery or some other reason, the result is a loss of body fat. This obviously impacts the way a person is insulated from cooler temperatures. When a person is losing weight rapidly, their metabolism also slows down, which can cause issues with overall body temperature regulation, too.

Anemia Can Also Contribute To Feeling Colder Than Usual

After undergoing any kind of bariatric surgery, it is common for patients to become anemic. Anemia, the deficiency in red blood cells or hemoglobin in your blood, can cause feelings of fatigue and can also contribute to feeling colder than usual.

Why does this happen after weight loss surgery? It mostly occurs due to an iron deficiency. Like we’ve discussed in previous blogs, it’s easy to get an iron deficiency after bariatric surgery, especially if you’ve undergone a malabsorptive surgery, as it can be difficult to get all the iron you need.

Feeling Hotter Than Usual?

While the majority of bariatric surgery patients feel colder than usual, it is common for patients to feel warmer than usual, too. This is typically just your body’s response to a major change in fat storage and weight.

Are These Hot And Cold Sensations Permanent?

No, not necessarily. As your body weight stabilizes, which is normally after 18 to 24 months, you will likely notice the fluctuations in your body temperature subside. We know that it can be a frustrating time, but your body is really good at adapting to change.

What Are Your Options For Addressing These Issues?

Addressing cold intolerance involves addressing the root cause in a realistic and sensible way. If you’re anemic or have issues with iron deficiency, consuming a healthier diet or taking iron supplements will be your best option. During the surgical consultation, we’ll discuss how you can get the most ideal diet for several different nutritional deficiencies. Sometimes you may need to carry a light jacket or sweater with you until your body temperature evens out.
