What kind of doctor treats Disorders of Lipoid Metabolism?
A primary care doctor usually diagnoses and treats lipid disorders. If levels are hard to control, the doctor may send the patient to a lipidologist or a cardiologist. A dietitian often helps with meal planning. 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 it is
Lipoid metabolism disorders are conditions that affect how the body handles fats. Doctors often call these conditions lipid disorders or dyslipidemia, meaning the levels of fats in the blood are not normal. The two fats people hear about most are cholesterol, a waxy substance the body uses to build cells, and triglycerides, fats the body stores for energy. When these fats build up in the blood, they can harm blood vessels over time.
Symptoms
Most people with a lipid disorder feel completely fine, and there are usually no symptoms until damage has occurred. Some people with very high fat levels develop yellowish skin bumps called xanthomas. The real danger is silent: high cholesterol can narrow arteries, raising the chance of a heart attack or stroke.
Causes and who gets it
Some lipid disorders run in families, such as familial hypercholesterolemia, a genetic condition causing very high cholesterol from birth. Other causes include a diet high in saturated fat, inactivity, obesity, diabetes, an underactive thyroid, and certain medicines. Risk goes up with age.
How doctors diagnose it
Doctors find lipid disorders with a blood test called a lipid panel, for which you may need to fast. The panel reports total cholesterol, LDL (bad) cholesterol, which can clog arteries, HDL (good) cholesterol, which helps clear fat from the blood, and triglycerides. If results are unusual, the doctor may order genetic testing.
Treatment
Treatment usually starts with lifestyle changes: eating less saturated fat, exercising, quitting smoking, and losing weight if needed. Many people also need medicine. Statins are the most common; they slow the liver's production of cholesterol. Regular blood tests check that treatment is working.
When to see a doctor
See a doctor if you have never had your cholesterol checked, especially if heart disease runs in your family. Adults should get tested at least every few years. Get medical help right away for chest pain, trouble breathing, weakness on one side, or trouble speaking, which can signal a heart attack or stroke.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either type can handle most lipid disorders, with longer visits that make it easier to discuss diet, exercise, and medicines.
Common questions
Can a lipid disorder be cured?
Most lipid disorders are managed rather than cured. Inherited forms usually need lifelong care. With treatment, many people bring their fat levels down to a safer range, though results differ from person to person.
Do I need to fast before a cholesterol test?
Sometimes. Many doctors now accept non-fasting tests, but a fasting test may be ordered if triglycerides need a closer look. Your doctor will tell you what to do.
Are all fats bad for me?
No. Fats found in olive oil, nuts, and fish are generally considered healthier choices. The fats to limit are saturated fats and trans fats, which are often found in fried and processed foods.
Can children have high cholesterol?
Yes, especially if it runs in the family. Guidelines suggest screening children with a family history of early heart disease or very high cholesterol.
