I have Turner syndrome. Should I screen for insulin resistance?

Question

Hi doctor,

I have been told that my triglyceride levels are very high, despite trying to eat healthy and stay active. I do not have diabetes, but I often feel tired, bloated after meals, and I have gained weight, mostly around my abdomen.

Recently, genetic testing revealed that I have Turner Syndrome, which was diagnosed due to my short stature, irregular periods, and infertility. I have read that women with Turner Syndrome are at a higher risk for metabolic issues. Could that be why my triglycerides are difficult to control?

I am worried about the long-term risks like pancreatitis or heart disease, especially since heart conditions are already common in Turner Syndrome. Are there specific dietary or medication strategies I should follow given my genetic background?

Should I be screened for other lipid abnormalities or insulin resistance more often? I am also concerned about the impact of hormone replacement therapy; could it be contributing to my lipid problems?

Please advise.

Hi

Welcome to icliniq.com.

Your concerns are absolutely valid. Turner Syndrome (TS) significantly increases the risk for metabolic issues, including high triglycerides, weight gain, insulin resistance, and cardiovascular disease, largely due to a combination of genetic, hormonal, and structural factors. Your high triglycerides, abdominal weight gain, fatigue, and post-meal bloating point to possible underlying insulin resistance, even if you do not have diabetes yet. This, coupled with TS, makes triglyceride control more challenging and raises your risk for complications like pancreatitis and premature heart disease.

Women with TS often have estrogen deficiency, which contributes to unfavorable lipid profiles. While hormone replacement therapy (HRT) can improve some cardiovascular risk markers, in some cases, it can also worsen triglycerides, especially if oral estrogen is used. You might benefit from switching to transdermal estrogen, which has a more favorable metabolic profile.

Given your Turner diagnosis and elevated triglycerides, it is important to screen regularly for:

Insulin resistance (fasting insulin, Homeostatic Model Assessment for Insulin Resistance HOMA-IR, glycated hemoglobin HbA1c)
Apolipoprotein B (ApoB) and non-high-density lipoprotein (HDL) cholesterol.
Liver function tests and an ultrasound (for fatty liver).
Pancreatic enzymes.

Follow a low-glycemic, Mediterranean-style diet, rich in fiber, lean protein, and omega-3s (like fatty fish, chia seeds, flax).

Also, minimize use of refined carbs, sugars, and alcohol (all elevate triglycerides). Include aerobic exercise on most days of the week.

If triglycerides remain more than 500 mg/dL, medications like fibrates, omega-3 prescription doses, or newer agents like Icosapent ethyl may be considered, especially if pregnancy is not a current goal. Consult your specialist doctor before starting any medication.

I hope this solves your query, and I will be happy to help you further.

Thank you.
