Low Body Temperature: Should You See a Doctor?

I would like to inquire about the state of hypothermia?

Hello Doctor: I previously had an examination at the metabolic department.
Aside from being overweight and having a BMI above the normal range, all other values related to pituitary secretion, adrenaline, thyroid function, and cholesterol were normal.
The doctor could only suggest that I attend nutritional education.
However, I have been particularly mindful of protein levels, carbohydrates, fats, glycemic index, and the vitamins and sodium content in food due to my elders having hypertension and diabetes (which is age-related and not hereditary).
Therefore, I did not attend the nutritionist's sessions.
I also maintained a body temperature around 35 degrees Celsius, thinking it was normal, but I recently discovered that my temperature is considered low (34.8-35.4).
My forehead temperature, ear temperature, systolic blood pressure is 112, and diastolic blood pressure is 72 (sometimes even lower).
My fasting blood sugar is between 60-80, and postprandial blood sugar is 105.
The doctor mentioned that if I want to improve my health, I should take medication to lower my blood sugar.
Should I see a doctor regarding my low body temperature? If I take medication to lower my blood sugar, will it drop too low? Thank you for taking the time to respond!

Understanding low body temperature is crucial, especially when it comes to assessing your health and determining whether you need to see a doctor. In your case, you mentioned that your body temperature consistently hovers around 35 degrees Celsius (95 degrees Fahrenheit), which is indeed lower than the normal range of approximately 36.1 to 37.2 degrees Celsius (97 to 99 degrees Fahrenheit). A body temperature below 35 degrees Celsius can be classified as hypothermia, which can have serious health implications if not addressed.

First, it’s important to understand the potential causes of low body temperature. Factors such as environmental exposure, metabolic disorders, and even certain medications can contribute to this condition. In your case, you have already undergone tests that ruled out issues with your pituitary gland, adrenal function, and thyroid levels, which are common culprits for low body temperature. However, it’s worth noting that conditions like hypothyroidism can sometimes present with subtle symptoms, and it may be beneficial to have a thorough evaluation of your thyroid function, including TSH, T3, and T4 levels.

Your blood pressure readings (systolic 112 and diastolic 72) are within a normal range, which is a positive sign. However, the concern arises with your blood sugar levels. A fasting blood sugar of 60-80 mg/dL is on the lower end of the normal spectrum, and a postprandial level of 105 mg/dL is acceptable. If your doctor has suggested that you might need medication to manage your blood sugar, it’s essential to discuss this thoroughly with them. The goal is to ensure that any medication prescribed does not lead to hypoglycemia, especially given your already low body temperature.

As for whether you should see a doctor specifically for your low body temperature, the answer is yes. It is advisable to consult with a healthcare professional who can conduct a comprehensive evaluation of your symptoms and overall health. They may recommend further tests to rule out any underlying conditions that could be contributing to your low body temperature. Additionally, they can provide guidance on lifestyle modifications, dietary changes, and possibly even supplements that could help improve your metabolic rate and body temperature regulation.

In the meantime, there are several strategies you can implement to help manage your low body temperature and improve your overall well-being:
1. Dress Appropriately: Layer your clothing, especially in colder environments, to help retain body heat.

2. Nutrition: Focus on a balanced diet rich in whole foods, including proteins, healthy fats, and complex carbohydrates. Foods that are warming in nature, such as ginger, garlic, and spices, can also help.

3. Stay Active: Regular physical activity can boost your metabolism and help generate body heat. Aim for a combination of aerobic and strength-training exercises.

4. Hydration: Ensure you are well-hydrated, as dehydration can affect your body’s ability to regulate temperature.

5. Monitor Your Symptoms: Keep track of any changes in your body temperature, energy levels, and overall health. If you notice any significant changes, seek medical advice promptly.

6. Consult a Specialist: If your primary care physician is unable to provide answers, consider seeing an endocrinologist or a specialist in metabolic disorders for further evaluation.

In conclusion, while your low body temperature may not seem alarming at first glance, it is essential to take it seriously and seek medical advice. Understanding the underlying causes and addressing them appropriately can help you maintain a healthier body temperature and overall well-being.
