Your neck may be telling you more about your health than you realize. Health experts warn that neck circumference is linked to serious conditions like heart failure, type 2 diabetes, and sleep apnea—even in people with a normal BMI.
For years, doctors primarily relied on Body Mass Index (BMI) to assess health risks. Now, researchers suggest that neck thickness may be a stronger indicator of hidden fat deposits in the upper body. Unlike visible fat, this type of fat surrounds vital organs, releasing fatty acids that can disrupt cholesterol, blood sugar regulation, and heart rate.
Health Risks Linked to a Thick Neck
Studies show that people with a thick neck are more likely to develop:
- High blood pressure and atrial fibrillation (irregular heartbeat)
- Heart failure and coronary artery disease
- Type 2 diabetes and metabolic issues
- Sleep apnea and fatigue-related risks, including accidents
Doctors warn that irregular heartbeats caused by excess fat around the neck can increase the risk of strokes and long-term heart damage.
What is Considered a Thick Neck?
Experts define a thick neck as 17 inches or more in men and 14 inches or more in women. Even small increases beyond this threshold raise the risk of hospitalization and early death, regardless of overall weight.
How to Lower the Risk
Doctors recommend:
- Cardio and weight training to reduce upper body fat
- Adequate sleep to support metabolic health
- A balanced diet rich in legumes, fruits, and and vegetables
Your neck could be a simple yet powerful clue about your health. While BMI is still widely used, paying attention to neck circumference could help you detect health problems earlier and encourage the lifestyle changes needed to prevent serious conditions.
