Hypothyroidism: Symptoms, Risks, and When to Seek Help - Internal Medicine

More Info

---

Hypothyroidism, or an underactive thyroid, is a condition where the thyroid gland does not produce enough thyroid hormones. This can lead to a variety of symptoms and health issues, particularly if left untreated. Given your situation, where you have not taken thyroid hormone replacement for a year and have experienced new symptoms such as chest pain, difficulty breathing, elevated blood pressure, and increased heart rate, it is crucial to understand the implications of these symptoms and the importance of seeking medical attention.


Symptoms of Hypothyroidism
Common symptoms of hypothyroidism include:
1. Fatigue: A persistent feeling of tiredness or lack of energy.

2. Weight Gain: Unexplained weight gain or difficulty losing weight.

3. Cold Intolerance: Increased sensitivity to cold temperatures.

4. Dry Skin and Hair: Skin may become dry and hair may become brittle or fall out.

5. Constipation: Slower digestive processes can lead to constipation.

6. Depression: Mood changes, including feelings of depression or anxiety.

7. Muscle Weakness: Generalized weakness or muscle cramps.

In your case, the new symptoms of chest pain and difficulty breathing could be concerning. While these symptoms can arise from various conditions, they may also be related to your hypothyroidism, especially if it has worsened.


Risks of Untreated Hypothyroidism
Untreated hypothyroidism can lead to several complications, including:
- Cardiovascular Issues: Low thyroid hormone levels can lead to increased cholesterol levels, which may contribute to heart disease. Symptoms like chest pain and elevated heart rate could indicate cardiovascular strain.

- Myxedema Coma: This is a rare but life-threatening condition that can occur due to severe hypothyroidism, characterized by extreme cold intolerance, drowsiness, and even unconsciousness.

- Mental Health Issues: Prolonged hypothyroidism can lead to significant mood disturbances, including depression and cognitive decline.


When to Seek Help
Given your symptoms and the fact that you have not been on thyroid hormone replacement for a year, it is essential to seek medical attention promptly. Here are some steps you should consider:
1. Return to Your Endocrinologist: Schedule an appointment with your endocrinologist to discuss your symptoms and the lack of treatment. It is crucial to have your thyroid hormone levels checked through blood tests (TSH, Free T4, and possibly Free T3).


2. Inform Your Doctor: When you visit your endocrinologist, be sure to inform them about your recent visits to the cardiologist and any medications you are currently taking for your heart. This information is vital for your doctor to understand your overall health and to make informed decisions regarding your treatment plan.

3. Monitor Symptoms: Keep a detailed record of your symptoms, including when they occur, their severity, and any potential triggers. This information can help your healthcare provider assess your condition more accurately.

4. Lifestyle Adjustments: While awaiting your appointment, consider lifestyle changes that may help manage your symptoms, such as a balanced diet, regular exercise (as tolerated), and stress management techniques.


Conclusion
In summary, your symptoms of chest pain and difficulty breathing, combined with a history of untreated hypothyroidism, warrant immediate medical evaluation. It is essential to return to your healthcare provider for a thorough assessment and to discuss your treatment options. Hypothyroidism can significantly impact your quality of life and overall health, so proactive management is key. Remember, communication with your healthcare team is crucial for effective treatment and management of your condition.
