3 Blood Tests To Ask Your Doctor For If You Feel Depressed
When you're struggling with low mood or the heavy feelings of depression, it can be a lonely and confusing time. While therapy and lifestyle changes are helpful, it's also important to consider the physical factors that might be contributing to how you feel. Many people don't realise that certain physical health conditions can mimic the symptoms of depression.In your journey to healing, it's a wise first step to have an open conversation with your doctor. Asking for a few key blood tests can help rule out underlying physical issues. Here are three blood tests to discuss with your GP if you're feeling depressed.
1. Full Blood Count (FBC)
The Full Blood Count is a common test that provides a detailed look at the cells in your blood, including red blood cells, white blood cells and platelets. An FBC can highlight anaemia, a condition where your blood cells don't carry enough oxygen to your tissues.
Anaemia can lead to symptoms like:
-
Chronic fatigue and a lack of energy.
-
Feeling weak or lightheaded.
-
Headaches.
-
Difficulty concentrating.
These symptoms can easily be mistaken for signs of depression. By checking your FBC, your doctor can determine if anaemia is playing a role in your low mood and recommend a simple treatment, often an iron supplement, which can make a world of difference.
2. Thyroid Function Test (TFT)
Your thyroid gland plays a huge role in regulating your metabolism, energy levels, and mood. An underactive thyroid, a condition known as hypothyroidism, can be a major contributor to symptoms that look a lot like depression.
Symptoms of an underactive thyroid can include:
-
Persistent fatigue and low energy.
-
Feeling cold.
-
Unexplained weight gain.
-
Brain fog and difficulty thinking clearly.
A simple blood test can measure the levels of hormones produced by your thyroid. If your thyroid levels are abnormal, your doctor can prescribe medication to get them back in balance, which can significantly improve your mood and energy.
3. Diabetes Test (Blood Glucose / HbA1c)
Fluctuations in your blood sugar can have a powerful impact on your mood and energy. Diabetes, or unstable blood sugar levels, can be a sneaky cause of feeling low.
When your blood sugar is too high or too low, you might experience:
-
Irritability and mood swings.
-
Fatigue and a general feeling of unwellness.
-
Difficulty concentrating.
-
Anxiety.
A test called HbA1c (Glycated Haemoglobin) provides an average of your blood sugar levels over the past three months. This test can help your doctor determine if you have prediabetes or diabetes, and getting this under control through diet, lifestyle changes, or medication can help stabilise your mood and energy.
The Bottom Line
While the emotional and spiritual aspects of healing from depression are incredibly important, it's crucial not to overlook the physical side. By being proactive and asking your GP for these three simple blood tests, you can rule out some common physical causes of low mood. Remember, your body is a trust from Allah, and taking care of it is part of your healing journey.
