Can High Cholesterol Cause Headaches?

High cholesterol is a common health condition that affects millions of people worldwide. While the primary concerns with high cholesterol tend to be an increased risk of heart disease and stroke, many people are also curious about the potential link between high cholesterol and headaches.

So, can high cholesterol actually cause headaches? The short answer is that the connection between high cholesterol and headaches is not entirely clear or well-established. Let’s take a closer look at what the research says.


Currently, there is no definitive link between high cholesterol and headaches. However, individuals with high cholesterol may experience frequent headaches. This is likely because many of the same lifestyle factors that contribute to high cholesterol can also increase the risk of headaches.

The Potential Link Between High Cholesterol and Headaches:

There are a few different ways that high cholesterol could potentially contribute to or cause headaches, though the evidence is limited:

1. Vascular Effects

High levels of LDL (“bad”) cholesterol can contribute to the buildup of plaque in the arteries, a condition known as atherosclerosis. This plaque buildup can impair blood flow and restrict the supply of oxygen-rich blood to the brain. This reduced blood flow could potentially trigger or exacerbate headaches.

Some research has found a correlation between high cholesterol levels and a higher incidence of migraines. One study published in the Journal of Neurology, Neurosurgery & Psychiatry observed that people with high cholesterol were more likely to experience migraine headaches compared to those with normal cholesterol levels.

2. Inflammation

High cholesterol levels are associated with increased inflammation in the body. This chronic inflammation can potentially contribute to or worsen headache conditions like migraines. Inflammation can cause the blood vessels in the brain to swell and become irritated, leading to painful headaches.

3. Hormonal Factors

There is also some evidence that high cholesterol may impact certain hormones that can influence headache susceptibility. For example, cholesterol is a precursor to the production of hormones like estrogen and testosterone. Imbalances in these hormones have been linked to an increased risk of migraines, particularly in women.

However, it’s important to note that the research on the direct connection between high cholesterol and headaches is limited and inconclusive. Many of the studies have been observational in nature, meaning they’ve found correlations between the two conditions but haven’t proven a clear cause-and-effect relationship.


Other Potential Causes of Headaches:

While high cholesterol may play a role in some cases, there are many other potential causes of headaches that are more well-established:

– Stress and tension

– Dehydration

– Lack of sleep

– Dietary triggers (e.g. certain foods, caffeine withdrawal)

– Changes in hormone levels

– Sinus infections or allergies

– Eye strain

– Neck or back problems

– Certain medications

For many people, headaches are likely the result of a combination of factors rather than a single underlying cause. Ruling out these other potential triggers is important before assuming high cholesterol is the culprit.


When to See a Doctor:

If you are experiencing frequent or severe headaches, it’s always a good idea to consult with your healthcare provider, regardless of your cholesterol levels. They can help determine the underlying cause and provide appropriate treatment.


Some signs that you should see a doctor about your headaches include:

– Sudden, severe onset of a headache

– Headaches that interfere with your daily life and activities

– Headaches accompanied by other concerning symptoms like vision changes, slurred speech, or numbness

– Headaches that seem to be getting progressively worse over time

Your doctor can perform any necessary testing, including checking your cholesterol levels, to identify the root cause of your headaches. They may also recommend lifestyle changes, medication, or other therapies to provide relief.

Managing High Cholesterol to Reduce Headache Risk:

While the link between high cholesterol and headaches is not conclusive, maintaining healthy cholesterol levels is still important for overall health and reducing the risk of serious conditions like heart disease.


Here are some tips for managing high cholesterol and potentially reducing headache risk:

  1. Adopt a heart-healthy diet. Eating more fruits, vegetables, whole grains, lean proteins, and healthy fats can help lower LDL cholesterol and triglycerides.
  2. Get regular exercise. Aim for at least 150 minutes of moderate-intensity physical activity per week. This can help raise HDL (“good”) cholesterol and improve circulation.
  3. Lose extra weight. Carrying extra body weight, especially around the midsection, is a risk factor for high cholesterol. Losing even a small amount of weight can make a difference.
  4. Quit smoking. Smoking can significantly increase LDL cholesterol and lower HDL cholesterol. Quitting can help improve your cholesterol profile.
  5. Manage stress. Chronic stress can contribute to inflammation and negatively impact cholesterol levels. Try stress-reducing activities like meditation, yoga, or deep breathing.
  6. Work with your doctor. If lifestyle changes alone are not enough, your doctor may prescribe cholesterol-lowering medications like statins to help get your levels under control.

By taking proactive steps to manage your cholesterol, you may be able to reduce your overall risk of both heart disease and potentially headaches as well. However, it’s important to keep in mind that headaches can have many complex causes, so high cholesterol may only be one piece of the puzzle.



The relationship between high cholesterol and headaches is not entirely clear or well-established based on the current research. While some studies have found a potential link, particularly with migraines, the evidence is limited and inconclusive.

High cholesterol may contribute to headaches through mechanisms like impaired blood flow or increased inflammation, but other factors like stress, diet, and hormones also play a significant role. If you are experiencing frequent or severe headaches, it’s important to see your doctor to identify the underlying cause and get appropriate treatment.

Maintaining healthy cholesterol levels through diet, exercise, and other lifestyle changes is still important for overall health and potentially reducing headache risk. But headaches can have many complex causes, so managing cholesterol alone may not be enough to provide complete relief. Working closely with your healthcare provider is key to getting to the bottom of your headache issues.
