Headaches after bariatric surgery is surprisingly more common than patients are led to believe. In this blog, we will talk about why people get headaches after bariatric surgery and some remedies you can use, and how we typically treat these.

One of the critical things to note about headaches is whether or not you have them before surgery. If you had migraines and cluster headaches pre-surgery, those will tend to persist after surgery as well, so whatever treatment you were using pre-surgery, you should continue.

Headaches After Bariatric Surgery

Some patients get headaches after bariatric surgery and the number one reason is dehydration. If you are not drinking enough and are in a dehydrated state, you tend to have those headaches. So the first remedy is to make sure that you are well-hydrated. It is important to look for signs of dehydration early on.

Dehydration

If your mouth gets that cotton feeling, you’re probably dehydrated already. If your urine has decreased below four times a day and gets darker, you are probably dehydrated.

If you are dehydrated, we recommend constantly drinking water to maintain hydration. Your stomach is much smaller than it was before, so you cannot drink a whole lot of fluids in a short amount of time. Instead you will want to take small sips throughout the day.

We typically recommend doing this on a timer. Drink water first thing in the morning because you haven’t ingested anything for six to eight hours that you slept the night before. And then, every half hour, you want to be drinking a cup of water to stay hydrated. Most times, that’ll take care of a fair amount of the headaches.

Other Causes

If addressing your dehydration does not help the headaches, you can take medication. We typically recommend taking Tylenol since it’s a good choice for short term use. You can also use things like non-steroidal aspirin. However, we caution you not to take medication beyond three days because you will risk getting an ulcer.

If your headache has persisted for more than about five days, then we recommend you go in and visit your primary care physician so they can rule out some other causes of headaches, such as spontaneous intracranial hypotension. In one study on gastric bypass patients, they found that a small percentage of patients could develop this spontaneous intracranial hypotension due to a leak of the cerebrospinal fluid (CSF) out of the spinal canal. The leak will cause headaches when standing up but relief from lying down due to the pressure of the spinal fluid.

We recognize that headaches after bariatric surgery can be painful, debilitating, and concerning. Although they are often triggered by dehydration, if they persist you want to be sure to take the necessary action to ensure your health and safety. We recommend you schedule an appointment with your primary care physician to make sure your headaches are not related to anything serious.
