Overview
Hypertriglyceridemia — markedly elevated triglycerides — is common in Alström Syndrome and is one of the consequences of the severe insulin resistance that defines the condition. Very high levels can cause complications including pancreatitis. This article explains why triglycerides run high in Alström, what the levels mean, and how the issue is managed.
What triglycerides are
Triglycerides are a form of fat that circulates in the bloodstream and is stored in fat tissue. They come from the diet (fat we eat) and from the liver (which makes triglycerides from carbohydrates and other sources). Normal fasting triglyceride levels are below 150 mg/dL. Levels above 500 mg/dL are considered high; above 1,000 mg/dL is severe and increases the risk of pancreatitis.¹
Why triglycerides are high in Alström
Several mechanisms contribute:
- Severe insulin resistance — when insulin doesn't work well, the liver produces more triglycerides
- Adipose tissue dysfunction — fat cells in Alström don't store and release triglycerides normally
- Diet-related contribution — high-carbohydrate, high-sugar diets worsen triglycerides
- Type 2 diabetes — uncontrolled diabetes worsens triglycerides
- Obesity — adds to the burden
What high triglycerides do
Severely elevated triglycerides are linked to:
- Acute pancreatitis — inflammation of the pancreas, especially with levels above 1,000 mg/dL
- Cardiovascular risk — though the relationship is complex
- Eruptive xanthomas — yellowish skin bumps from very high triglycerides (uncommon)
- Lipemia retinalis — milky appearance of retinal blood vessels in extreme cases
- Hepatic steatosis — fatty liver
How triglycerides are managed
Lifestyle interventions
- Reduce added sugars — especially fructose, which strongly raises triglycerides
- Reduce refined carbohydrates — white bread, pastries, sugary drinks
- Limit alcohol — alcohol significantly raises triglycerides
- Increase omega-3 fats — fish, walnuts, flax, chia
- Regular exercise — improves triglyceride levels
- Weight management — modest weight reduction helps significantly
Medications
When lifestyle isn't enough or levels are very high:
- Fibrates (fenofibrate, gemfibrozil) — directly lower triglycerides; first-line for severe hypertriglyceridemia
- Omega-3 prescription products (icosapent ethyl, others) — high-dose pharmaceutical-grade EPA
- Statins — primarily for LDL cholesterol but help triglycerides modestly
- Niacin — older option, used selectively due to side effects
Treating the underlying conditions
- Optimizing diabetes control
- Treating fatty liver
- Managing other metabolic features
Screening schedule
Lipid screening is part of routine surveillance:
- Annual fasting lipid panel from childhood
- More frequent monitoring in adults with cardiovascular risk or active treatment
- Specific monitoring after starting or changing lipid medications
The 2020 international consensus guidelines support annual lipid assessment.²
Pancreatitis
Severe hypertriglyceridemia is a known cause of acute pancreatitis. Symptoms include:
- Severe upper abdominal pain
- Nausea and vomiting
- Pain radiating to the back
- Fever
- Tenderness when pressing the abdomen
Acute pancreatitis is a medical emergency. Anyone with severe hypertriglyceridemia should know the symptoms and seek same-day care if they develop.
Common questions
Frequently asked questions
Short answers grounded in the article and the underlying references, so families can quickly understand the main point without losing the medical meaning.
Question
What level of triglycerides is dangerous?
Answer
Levels above 500 mg/dL warrant medical attention; above 1,000 mg/dL substantially raises pancreatitis risk and is treated urgently. Even levels in the 200–500 range warrant lifestyle and sometimes medical management.
Question
Can diet alone control triglycerides?
Answer
For moderate elevations, often yes — particularly when added sugars and alcohol are reduced. For severe elevations or in the context of Alström's severe insulin resistance, medications often add benefit.
Question
Will my child need lipid medications?
Answer
It depends on their levels and overall metabolic picture. Many children with Alström don't need medications; some do as they get older. Your endocrinologist or lipid specialist makes the call.
Question
Are over-the-counter fish oil supplements adequate?
Answer
OTC fish oil can help moderate elevations. For severe triglycerides, prescription omega-3 products provide higher doses with better quality control. Discuss with your team.
