Familial Hypertriglyceridemia: Causes, Symptoms, and Treatment

What kind of doctor treats Familial Hypertriglyceridemia?
A primary care doctor often manages this condition. Hard-to-control levels may prompt referral to a gastroenterologist or lipid specialist; cardiologists may be involved if heart disease is a concern. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is familial hypertriglyceridemia?
Familial hypertriglyceridemia is an inherited condition that causes high levels of triglycerides, a type of fat in the blood. People are born with it, and it runs in families. High triglycerides usually cause no symptoms but can raise the risk of pancreas and heart problems over time.
Triglycerides are fats your body uses for energy. In this condition, an inherited gene makes the body handle them poorly, so they build up in the blood. Doctors often find it during routine blood work, and people feel fine even when levels are high.
Symptoms
Most people have no symptoms. When levels become very high, some develop pancreatitis, a painful swelling of the pancreas, with severe belly pain, nausea, and vomiting. Extremely high levels can also cause yellowish skin bumps called eruptive xanthomas.
Causes and who gets it
Changed genes that affect how the body clears fat from the blood cause this condition; a child usually needs to inherit the changed gene from only one parent. It often appears in adulthood and can be worsened by obesity, diabetes, alcohol, certain medicines, and an underactive thyroid.
How doctors diagnose it
Doctors use a blood test called a lipid panel, usually after several hours of fasting. If triglycerides are very high, they consider family history, other conditions, and medicines to rule out other causes. Genetic testing is sometimes used.
Treatment
Treatment starts with lifestyle changes: eating less sugar and refined carbohydrates, limiting alcohol, losing weight, and exercising. If those are not enough, doctors may prescribe medicines that lower blood fats. This lowers triglycerides and the risk of complications, but does not change the genes.
When to see a doctor
See a doctor if you have a family history of high triglycerides or early heart disease. Get help right away for severe belly pain with nausea or vomiting, which can signal pancreatitis. Regular checkups with blood work are wise.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance; a concierge doctor usually charges more and often works alongside insurance. Either can order lipid panels, adjust lifestyle plans, prescribe medicines, and track progress, referring you to a specialist if needed.
Common questions
Can familial hypertriglyceridemia be cured?
No, the gene change that causes it cannot be removed. However, treatment can often bring triglyceride levels down and lower the risk of complications. How well treatment works varies from person to person.
Is it the same as high cholesterol?
Not exactly. Cholesterol and triglycerides are both fats in the blood, but they behave differently in the body. People with this condition can have normal cholesterol with very high triglycerides, though some have both.
Do I need to fast before a triglyceride test?
Often yes, because eating recently can raise the reading. Your doctor will tell you how long to avoid food before the test. Some labs now offer non-fasting tests, but very high levels are usually confirmed with a fasting repeat.
Can children have this condition?
Yes, though it more often becomes noticeable in adulthood. Children in affected families sometimes have high triglycerides found on blood tests. A pediatrician can order the same lipid panel used for adults.
