Understanding FH in Children: What Parents in Jackson, TN Need to Know About Familial Hypercholesterolemia

When most people think of high cholesterol, they picture middle-aged adults needing to cut back on fried foods or start walking more often. But did you know that some children are born with cholesterol levels that are dangerously high—completely unrelated to what they eat or how active they are? This inherited condition is called familial hypercholesterolemia (FH), and while it affects about 1 in every 250 kids, very few families have ever heard of it.

Here at The Children’s Clinic in Jackson, TN, we see firsthand how confusing and overwhelming it can be for parents to navigate something as unexpected as high cholesterol in children. Our goal is to make sure families understand what FH is, how it’s diagnosed, and the treatment options available so children can live long, healthy lives.

What Is Familial Hypercholesterolemia (FH)?

Familial hypercholesterolemia is a genetic condition that causes cholesterol levels—specifically LDL (the "bad" cholesterol)—to be extremely high from birth. Unlike lifestyle-related cholesterol problems, FH isn’t caused by diet, weight, or exercise. Instead, it’s the result of an inherited gene mutation that makes it harder for the body to clear LDL cholesterol from the blood.

Over time, this can lead to cholesterol building up in arteries, increasing the risk of heart disease at a much earlier age than usual.

Why FH Is Often Missed

One of the biggest challenges with FH is that it usually has no obvious symptoms in children. A child with FH may look and feel completely healthy. In many cases, parents only discover the condition after routine bloodwork shows unusually high cholesterol levels—or worse, when a relative suffers a heart attack or stroke at a young age.

Statistics show that only about 30% of people with FH actually know they have it. That means millions of children and adults are living with the condition without proper diagnosis or treatment.

Types of FH

There are two main forms of familial hypercholesterolemia:

  1. Heterozygous FH (HeFH)

    • The more common type.

    • A child inherits one copy of the faulty gene from one parent.

    • LDL cholesterol levels are usually about double the normal range.

  2. Homozygous FH (HoFH)

    • Far more rare, but much more serious.

    • A child inherits faulty genes from both parents.

    • Cholesterol levels can be four times higher than normal.

    • Without early treatment, HoFH can cause serious heart problems in childhood or adolescence.

How Is FH Diagnosed?

Because FH doesn’t come with obvious warning signs, diagnosis usually happens through a cholesterol screening test. Pediatricians often recommend cholesterol checks for children if:

  • There’s a strong family history of early heart disease.

  • A parent or close relative is known to have FH.

  • The child’s blood test shows unusually high cholesterol levels.

In some cases, genetic testing may be used to confirm FH.

At The Children’s Clinic in Jackson, TN, we encourage parents to share any family history of heart disease with their child’s doctor. Even details about grandparents or aunts and uncles can help us determine whether a cholesterol screening is appropriate.

Why Early Diagnosis Matters

The good news is that early diagnosis makes a huge difference. Children with FH who receive the right care can lower their cholesterol levels and significantly reduce their risk of developing heart disease later in life.

Without treatment, FH increases the likelihood of:

  • Heart disease

  • Heart attacks at a young age

  • Stroke

But with consistent monitoring and treatment, children with FH can grow up healthy, active, and thriving.

Treatment Options for FH

Managing FH is not about “fixing” cholesterol overnight. It’s about building a long-term plan that supports a child’s health from childhood through adulthood. Treatment often includes:

  1. Lifestyle Guidance

    • While FH isn’t caused by diet or exercise, healthy habits can still help manage cholesterol levels.

    • A balanced diet with fruits, vegetables, lean proteins, and whole grains is encouraged.

    • Limiting fried foods, sugary drinks, and processed snacks supports overall health.

    • Staying active is important for cardiovascular health, even if it doesn’t directly correct FH.

  2. Medication

    • Many children with FH need medications such as statins to lower cholesterol levels.

    • Other medications may include bile acid sequestrants or newer therapies designed for severe cases.

    • These treatments are carefully prescribed and monitored by pediatricians and specialists.

  3. Regular Monitoring

    • Children with FH typically need regular cholesterol checks to track progress.

    • Pediatricians may also monitor heart health more closely over time.

Living with FH

One of the hardest parts for parents is accepting that FH is lifelong. But while the diagnosis may sound scary, families should remember that children with FH can and do live normal, healthy lives when the condition is properly managed.

In fact, raising awareness is one of the most powerful tools we have. When more families know about FH, more children can be diagnosed early—and that means more lives saved.

  1. Frequently Asked Questions

    Is FH rare?
    Not at all. FH affects about 1 in 250 people worldwide. That makes it one of the most common genetic conditions.

    Can my child outgrow FH?
    No. Because FH is inherited, it doesn’t go away with age. But treatment makes a tremendous difference in long-term health.

    Does FH mean my child can’t play sports or eat their favorite foods?
    Most children with FH can live active, normal lives. They may need some dietary adjustments, but balance—not restriction—is the goal.

    Should parents get tested too?
    Yes. Because FH runs in families, parents and siblings of a child with FH should also be screened for high cholesterol.

    Why Local Care Matters

    Every community is unique, and so are its families. Here in Jackson, TN, we know how important it is for parents to have trusted pediatricians they can call on for guidance. FH may be genetic, but it doesn’t have to define your child’s future. With the right care team and ongoing support, your child can thrive.

    Final Thoughts

    Familial hypercholesterolemia may not be a household term, but it’s something every parent should be aware of. The earlier it’s identified, the easier it is to treat—and the better the outcomes for children.
