Compare Triglyceride Disorders

Understanding the Differences Between FCS, MCS, sHTG & TIP

Triglyceride disorders can have similar features, including elevated triglyceride levels and an increased risk of pancreatitis.
The table below highlights key differences in their causes, triglyceride levels, risks and treatment focus.

FEATURE

What is it?

Rare genetic disorder

Multifactorial disorder

Clinical condition

Complication

Cause

Single-gene defect

Combination of genetic predisposition and secondary factors

Multiple possible causes (genetic or secondary)

Triggered by severe elevation in triglycerides

Triglyceride Levels

Usually > 1,000 mg/dL

Often > 500 mg/dL

≥ 500 mg/dL

Usually occurs with very high TGs (often > 1,000 mg/dL

Pancreatitis Risk

Very High

Elevated

Elevated

Active pancreatitis event

Typical Onset

Childhood or adolescence

Adulthood (varies)

Any age

Acute episode

Treatment Focus

Very low-fat diet, specialized therapies, lifestyle

Address genetic + secondary factors, medications, lifestyle

Lifestyle changes, treat underlying causes, medications

Medical treatment of acute pancreatitis, prevent recurrence

How Are These Conditions Related?

  • FCS, MCS, and sHTG are disorders or conditions associated with elevated triglycerides.
  • TIP is a serious complication that can occur when triglyceride levels become extremely elevated.
  • Not everyone with FCS, MCS, or sHTG develops TIP; but risk increases as triglyceride levels rise.

Questions to Ask Your Healthcare Provider

About Diagnosis

  • What are my triglyceride levels?
  • What condition best explains my elevated triglyceride levels?
  • Could there be a genetic cause?

About Treatment

  • What can I do to lower my triglyceride levels?
  • How often should my triglycerides be monitored?

About Risk

  • What is my risk of pancreatitis?
  • What signs and symptoms should I watch for?

About Family

  • Should family members be screened?
  • What condition best explains my elevated triglyceride levels?

FCS
Familial Chylomicronemia Syndrome

A rare, inherited disorder in which the body cannot properly break down triglycerides, leading to extremely high blood fat levels and a high risk of recurrent, potentially life-threatening pancreatitis.

Explore FCS →

MCS
Multifactorial Chylomicronemia Syndrome

A disorder in which a combination of genetic predisposition and  secondary factors, such as  diiet, diabetes, medications, or alcohol, leads to markedly elevated triglyceride levels and an increased risk of pancreatitis.

Explore MCS →

sHTG
Severe
Hypertriglyceridemia

Characterized by very high levels of triglycerides in the blood (typically ≥500 mg/dL), increasing the risk of acute pancreatitis and contributing to cardiovascular disease.

Explore sHTG →

TIP
Triglyceride-induced
Pancreatitis

An acute inflammation of the pancreas caused by extremely elevated triglyceride levels, often requiring urgent medical care and carrying a risk of serious complications.
