Managing Cholesterol Levels: Insights for Patients with Hyperthyroidism

About cholesterol?

Hello, doctor.
I am currently undergoing treatment for hyperthyroidism and am in the medication reduction phase.
My physical condition has mostly returned to normal.
However, due to the medication, I have gained about two to three kilograms compared to before the onset of the disease.
I previously had a blood glucose test, and the doctor said "it's fine." Recently, I experienced dizziness and consulted an otolaryngologist, where I had my first-ever cholesterol and triglyceride tests.
The results showed a total cholesterol level of 242 and triglycerides at 164, both of which the doctor indicated were "high." However, I did not have LDL and HDL tests, so I am unaware of the levels of good and bad cholesterol.

Over the past six months, my blood pressure readings have ranged from 120 to 150.
Initially, the endocrinologist suggested that this might be related to the thyroid medication, but recent measurements have mostly been around 130/85, sometimes lower and sometimes higher.
I am approximately 168 cm tall and currently weigh between 68 and 69 kg.
I do not smoke or drink alcohol and consume little meat; my lifestyle is simple, but I have a fondness for sweets, particularly pastries.
I wonder if this could be contributing to my high cholesterol levels.

My family has a history of heart disease; three of my brothers have had heart stents placed, and my mother had heart issues before she passed away (however, none of the extended family members have diabetes, and both parents lived into their nineties and beyond).
I am concerned about whether I am also at high risk.
Given my current situation, should I start taking cholesterol-lowering medication, or can I manage this through dietary control and exercise? Based on the aforementioned conditions, what would be the best approach for my health management? Thank you.

Hello,
In your letter, you mentioned the issue of elevated total cholesterol and triglycerides.
The normal total cholesterol level is below 200 mg/dL, and triglycerides should be below 150 mg/dL.
While your levels are indeed elevated, it is important to also consider high-density lipoprotein (HDL) and low-density lipoprotein (LDL) in the assessment.
Based on your body type, your Body Mass Index (BMI) exceeds 24, which classifies you as overweight.
Additionally, with a family history of heart disease, you are indeed at high risk for cardiovascular disease.

I recommend starting with dietary improvements and increasing physical activity.
Pay attention to a low-cholesterol diet (avoid organ meats, seafood, and fried foods) and engage in regular, moderate aerobic exercise.
After about three months, please schedule a follow-up appointment with the Family Medicine department.
At that time, the physician will arrange for blood tests to evaluate the effectiveness of conservative management and determine if medication is necessary.

I hope these recommendations are helpful to you.
Wishing you good health.

More Info

Managing cholesterol levels, particularly for patients with hyperthyroidism, requires a comprehensive approach that considers various factors, including medication effects, dietary habits, family history, and overall health status. Based on your situation, here are some insights and recommendations.

Understanding Your Cholesterol Levels
Your recent cholesterol test results indicate a total cholesterol level of 242 mg/dL and triglycerides at 164 mg/dL, both of which are above the recommended levels. While you have not had your LDL (low-density lipoprotein) and HDL (high-density lipoprotein) levels checked, these values are crucial for understanding the type of cholesterol present in your blood. Generally, high LDL levels are associated with an increased risk of heart disease, while higher HDL levels are considered protective.

The Impact of Hyperthyroidism and Medication
Hyperthyroidism can influence cholesterol levels. Patients with hyperthyroidism often experience lower cholesterol levels due to increased metabolism. However, as you transition to a lower dose of medication, your cholesterol levels may rise. The medications used to treat hyperthyroidism can also have side effects that impact weight and metabolism, potentially contributing to your weight gain and elevated cholesterol levels.

Family History and Risk Factors
Your family history of heart disease is a significant risk factor. With multiple family members having undergone procedures for heart issues, it is essential to be proactive in managing your cardiovascular health. While your parents lived long lives without diabetes, the presence of heart disease in your family suggests a genetic predisposition that warrants careful monitoring.

Lifestyle Factors
Your lifestyle choices play a crucial role in managing cholesterol levels. While you do not smoke or drink alcohol and have a relatively low meat intake, your fondness for sweets and pastries could contribute to elevated cholesterol and triglyceride levels. Foods high in saturated fats, trans fats, and sugars can negatively impact cholesterol levels.

Recommendations for Management
1. Dietary Adjustments: Focus on a heart-healthy diet. Incorporate more fruits, vegetables, whole grains, and lean proteins while reducing saturated fats and sugars. Consider foods rich in omega-3 fatty acids, such as fish, flaxseeds, and walnuts, which can help lower triglyceride levels.

2. Regular Exercise: Aim for at least 150 minutes of moderate-intensity aerobic activity each week. Exercise can help improve cholesterol levels, aid in weight management, and enhance overall cardiovascular health.

3. Weight Management: If you have gained weight during your treatment, consider strategies to gradually lose those extra pounds. Even a modest weight loss can positively impact cholesterol levels and overall health.

4. Monitoring and Follow-Up: Regular check-ups with your healthcare provider are essential. Discuss the possibility of checking your LDL and HDL levels to get a complete picture of your cholesterol status. Based on your overall risk profile, your doctor may recommend medication if lifestyle changes alone are insufficient.

5. Medication Consideration: If your cholesterol levels remain high despite lifestyle changes, your doctor may suggest cholesterol-lowering medications, such as statins. These can be effective in reducing LDL cholesterol and overall cardiovascular risk.

6. Manage Stress: Stress can also impact your health. Consider incorporating stress-reducing practices such as mindfulness, yoga, or meditation into your routine.

Conclusion
In summary, managing your cholesterol levels involves a multifaceted approach that includes dietary changes, regular exercise, and monitoring your health status. Given your family history and current cholesterol levels, it is advisable to consult with your healthcare provider about the best course of action, including whether medication is necessary. By taking proactive steps now, you can significantly reduce your risk of heart disease and improve your overall health.
