Can High Triglycerides and High Cholesterol Cause Headaches, Dizziness, or Nausea? Facts & Stats Explained

High triglycerides and high cholesterol do not directly cause headaches, dizziness, or nausea in most people. However, they can contribute indirectly to these symptoms by leading to serious complications such as reduced blood flow, inflammation, high blood pressure, stroke, or heart disease. These conditions may trigger headaches, dizziness, or nausea, especially in severe or high-risk cases. Most individuals with high cholesterol or triglycerides remain asymptomatic unless complications arise.

• Not by itself, but arterial blockages or severe blood flow reduction resulting from high cholesterol can cause dizziness, faintness, or loss of balance in rare cases.

Yes, but indirectly. High triglycerides, like LDL (“bad”) cholesterol, can negatively affect blood circulation and increase inflammation, which may contribute to headaches. Decreased blood supply caused by plaque buildup can lead to symptoms such as numbness, dizziness, confusion, blurred vision, or severe headaches. Studies have shown an association between high triglycerides and increased prevalence of migraine—particularly migraine with aura—among elderly individuals.

• The answer is the same as above: not directly. High cholesterol by itself usually doesn’t cause dizziness, but the diseases it leads to can result in dizziness.

• Rarely and not directly. Most medical sources and research indicate that high cholesterol is not directly linked to causing headaches. However, high cholesterol contributes to high blood pressure, narrowed arteries, or poor circulation, which can trigger headaches—especially in those with other cardiovascular risk factors.
• One large study of 25,000 adults found that people with high cholesterol were more likely to develop migraines over 20 years, likely due to inflammation and vessel changes caused by cholesterol.

• Not as a direct symptom. Dizziness and nausea are not primary symptoms of high cholesterol. However, they can occur in connection with serious complications caused by cholesterol buildup, such as heart attack or stroke, which require immediate medical attention.

Condition	Headaches	Dizziness	Nausea
High triglycerides	Can contribute indirectly	Possible if severe	No
High cholesterol (direct effect)	Rare, indirect in most cases	No direct link	No
High cholesterol (via complication)	More likely w/ complications	Seen in stroke, severe events	Possible in emergencies

High triglycerides and cholesterol do not generally cause headaches, dizziness, or nausea as direct symptoms. However, their long-term complications (like high blood pressure, stroke, and heart disease) can lead to these symptoms, particularly in high-risk scenarios. Most people with high cholesterol or triglycerides will not experience these symptoms unless severe cardiovascular problems are already developing.
