Why does a bariatric patient experience headaches after bariatric surgery?

Headaches can occur for a few reasons after bariatric surgery. For one, it’s common for bariatric patients to consume less fluid. This is often a result of having less volume available in their stomach. By drinking less water, the risk for becoming dehydrated is increased. Dehydration is one cause of headaches.
Additionally, these headaches can occur due to nutritional deficiencies. Along the same lines, because bariatric surgery involves physical changes to the anatomy of the digestive system, absorption of nutrients is often negatively affected. For example, a deficiency in vitamin B12 can contribute to headaches.
In rare cases, bariatric surgery can lead to spontaneous intracranial hypotension (SIH). This occurs when cerebrospinal fluid leaks and results in severe headaches that worsen when standing and improve when lying down. If you suspect you are suffering from SIH, reach out to your physician right away.
Safe Medications for Headache Relief
If you are suffering from headaches, there are limited medications that are safe to use in the post-operative phase. The best recommendation is to take acetaminophen or paracetamol. Acetaminophen is generally considered safe for pain relief after bariatric surgery. This aligns with the careful approach to medications after surgery, especially when considering weight loss medications after bariatric surgery.
However, nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and naproxen are not recommended. This is typically because of the increased risk of gastrointestinal issues and ulcers. After bariatric surgery, it’s best to steer clear of these drugs to prevent problems with your new digestive system.
If you have any other questions about which medications to safely take in the post-operative period, reach out to your doctor. Always discuss with your physician before taking any medication to ensure safety and appropriateness.
Non-Medication Remedies
Outside of medication, there are a few other headache remedies to consider.
First, make sure you are hydrated. As discussed, adequate fluid intake is key to prevent dehydration and headaches.
Keep a water bottle with you at all times and take small sips throughout the day. Your stomach may be smaller after bariatric surgery.
So, it’s not recommended to take big gulps or chug water at once. Instead, try to keep hydrated all day with small sips.

Additionally, eating a well-balanced diet is essential. This will help with healing after surgery. It will also ensure you do not become deficient in any nutrients. Aim to eat several small meals throughout the day. Choose foods that are high in protein like bariatric protein shakes and bariatric protein bars, and fiber to help you feel full. Choose whole foods over processed ones. They are more nutrient-dense.
Lastly, keep an eye on your stress. Though easier said than done, reduce stress wherever possible. Headaches can sometimes come from tension and stress. So, the more you use mindful relaxation, the better. Try stress management techniques, like meditation or deep breathing, to ease this symptom.
Role of Supplements in Headache Management
While a balanced diet is crucial, sometimes it isn’t enough on its own. This is where nutritional supplements can come into play. You may consider taking vitamin B12 supplements to prevent any deficiency-related headaches.
Additionally, some headaches can be caused by anemia. Be sure to be mindful of your iron and folate levels and if needed, seek supplementation of these nutrients.
Lastly, a good rule of thumb, especially after bariatric surgery is to start taking multivitamins.
Because your digestive system is not as good as absorbing nutrients post-surgery, multivitamins are essential to keep deficiencies at bay. Regular intake of multivitamins and address multiple deficiencies simultaneously.
How can I prevent headaches after bariatric surgery?
If you aren’t experiencing headaches yet, but want to make sure it stays that way, there are a few ways to prevent headaches from happening. For one, be sure to attend your follow up medical appointments. These check ups are essential to monitor nutritional status and make sure you are healing properly. Don’t skip them!
Also, follow the dietary guidelines you get after bariatric surgery. You will want to make sure you are clear on what is expected of you and your new diet. This will change a lot after surgery.

Lastly, be sure to stay hydrated. Drink the recommended amount of fluids throughout the day to avoid dehydration.
When to Seek Medical Help
While headaches are a common side effect of bariatric surgery and often not a cause for concern, there are a few signs to look out for that may indicate something more severe is happening.
If you are suffering from persistent or severe headaches, reach out to your doctor. If these headaches are ongoing seemingly with no relief or intensify in their pain, consult a healthcare professional.
If you begin to notice additional symptoms like neck stiffness, nausea, or even neurological changes, seek out immediate medical attention.
If you notice that your headaches worsen when standing and improve when lying down, contact your doctor right away. This could indicate SIH and may require prompt evaluation.
