Hypolipoproteinemia
What is Hypolipoproteinemia?
Hypolipoproteinemia is a rare condition where your body has abnormally low levels of lipoproteins in the blood. Lipoproteins are special proteins that carry fats, including cholesterol and triglycerides, throughout your body. While most people worry about high cholesterol, having too little cholesterol can also cause serious health problems.
Your body needs cholesterol to build healthy cells, make hormones, and produce vitamin D. When lipoprotein levels drop too low, your cells may not get the fats they need to function properly. This can affect your nervous system, digestion, and overall energy levels.
There are several types of hypolipoproteinemia, including familial hypobetalipoproteinemia and abetalipoproteinemia. Some forms are genetic and present from birth. Others develop later due to liver disease, malnutrition, or problems absorbing fats from food. Getting tested helps identify the type and guide treatment.
Symptoms
- Fatty, foul-smelling stools that are difficult to flush
- Chronic diarrhea or digestive problems
- Vitamin deficiencies, especially vitamins A, D, E, and K
- Vision problems or night blindness
- Muscle weakness and poor coordination
- Numbness or tingling in hands and feet
- Slow growth in children
- Liver enlargement
- Fatigue and low energy
- Difficulty maintaining healthy weight
Some people with mild hypolipoproteinemia have no obvious symptoms, especially in early stages. Others may only notice digestive issues at first. Severe forms can cause neurological problems that worsen over time without treatment.

Causes and risk factors
Most cases of hypolipoproteinemia are genetic and inherited from one or both parents. Mutations in genes that control how your body makes and processes lipoproteins prevent normal fat transport. Familial hypobetalipoproteinemia follows an autosomal dominant pattern, meaning you need only one mutated gene. Abetalipoproteinemia requires two mutated genes, one from each parent.
Acquired hypolipoproteinemia can develop from severe liver disease, malnutrition, hyperthyroidism, or chronic infections. Conditions that damage the intestines and reduce fat absorption also lower lipoprotein levels. Heavy alcohol use, certain medications, and inflammatory bowel diseases increase risk. Rare cases occur with cancer or bone marrow disorders that affect protein production.
How it's diagnosed
Diagnosis starts with a blood test measuring your total cholesterol and lipoprotein levels. Rite Aid offers testing for total cholesterol as part of our flagship panel with 200+ biomarkers. Abnormally low total cholesterol levels below 120 mg/dL may indicate hypolipoproteinemia. Your doctor will look at the complete lipid panel to see which specific lipoproteins are low.
Additional testing may include genetic testing, liver function tests, and vitamin level checks. Your doctor may also examine a blood smear under a microscope to look for abnormal red blood cells. A full evaluation helps determine whether the condition is inherited or acquired. This guides the right treatment approach for your specific situation.
Treatment options
- High-dose vitamin supplementation, especially fat-soluble vitamins A, D, E, and K
- Medium-chain triglyceride oil supplements to bypass normal fat absorption
- Low-fat diet with specific fatty acid supplements as directed by your doctor
- Regular monitoring of vitamin levels and neurological function
- Treatment of underlying conditions like liver disease or thyroid problems
- Essential fatty acid supplements to prevent deficiency
- Physical therapy for muscle weakness or coordination problems
- Working with a registered dietitian who specializes in fat malabsorption
Treatment focuses on preventing complications rather than raising cholesterol levels directly. Early diagnosis and consistent vitamin supplementation can prevent or slow neurological damage. Most people with hypolipoproteinemia need lifelong monitoring and nutritional support.

Frequently asked questions
Total cholesterol below 120 mg/dL is considered abnormally low and may indicate hypolipoproteinemia. Levels below 100 mg/dL are particularly concerning and warrant further investigation. Your doctor will evaluate your complete lipid profile and symptoms to determine if treatment is needed. Very low cholesterol can affect brain function, hormone production, and vitamin absorption.
Not exactly. Hypolipoproteinemia is a specific medical condition where your body cannot produce or process lipoproteins normally. Simple low cholesterol from diet or medication is different. Hypolipoproteinemia often comes with fat malabsorption, vitamin deficiencies, and neurological symptoms. It requires specialized medical treatment beyond just changing your diet.
Genetic forms of hypolipoproteinemia cannot be cured, but they can be managed effectively with treatment. Lifelong vitamin supplementation and dietary modifications help prevent complications. Acquired forms may improve if the underlying cause is treated successfully. Early diagnosis and consistent care allow most people to live relatively normal lives despite the condition.
Familial hypobetalipoproteinemia is inherited in an autosomal dominant pattern, meaning one mutated gene from either parent causes the condition. Abetalipoproteinemia requires two mutated genes, one from each parent. If you have a genetic form, your children have a 25% to 50% chance of inheriting it depending on the type. Genetic counseling can help you understand your family's specific risk.
People with hypolipoproteinemia typically need high doses of fat-soluble vitamins A, D, E, and K. These vitamins require fat for absorption, which is impaired in this condition. Vitamin E is especially important for preventing neurological damage. Your doctor will prescribe specific doses based on your blood levels and symptoms.
Diet alone cannot treat hypolipoproteinemia, but it plays an important supporting role. A low-fat diet with medium-chain triglyceride supplements helps reduce digestive symptoms. You still need vitamin supplementation and medical monitoring. Working with a dietitian experienced in fat malabsorption disorders helps you get proper nutrition while managing symptoms.
Hypolipoproteinemia can cause fatty liver disease as fat accumulates in liver cells. The liver may become enlarged and function less effectively over time. Regular monitoring of liver enzymes helps catch problems early. Treating vitamin deficiencies and following dietary recommendations can help protect your liver from further damage.
Most people with hypolipoproteinemia need blood testing every 3 to 6 months to monitor cholesterol and vitamin levels. Your doctor may test more frequently if you are starting new treatments or having symptoms. Annual neurological exams help catch nerve damage early. Regular testing helps adjust your treatment plan before complications develop.
Yes, hypolipoproteinemia can cause vision problems, especially from vitamin A deficiency. Night blindness is often an early sign. Severe cases may develop retinitis pigmentosa, which causes progressive vision loss. Regular eye exams and proper vitamin A supplementation help protect your vision.
Genetic forms of hypolipoproteinemia typically cause lifelong low cholesterol levels that cannot be normalized. Treatment focuses on preventing complications rather than raising cholesterol to normal ranges. Acquired forms may see cholesterol levels improve if the underlying cause is successfully treated. Your doctor will monitor your levels and adjust care based on your symptoms and overall health.
