The thyroid is part of your endocrine system that regulates when and how hormones release into your body. The thyroid can become overactive (produces too many hormones) or underactive (produces too few). Commonly those suffering from chronic fatigue syndrome are diagnosed with hypothyroidism which is also called underactive thyroid.
The common signs of underactive thyroid are almost a carbon copy of CFS symptoms, tiredness, weight gain, and feelings of depression. When your thyroid is not working efficiently, or you are suffering from thyroid resistance, your body is not receiving sufficient thyroid hormones, and your energy levels can drastically fall. Similar symptoms to chronic fatigue syndrome surface such as:
- Problems sleeping
- Joint pains and aching muscles
- Low libido
- Weight gain
- Constipation
- Psychiatric illnesses, depression, bipolar disorder
- Brain fog, memory problems, and problem-solving issues
- Muscle aches and weakness
- Muscle cramps
- Irregular heart rate, palpitations
Thyroid hormones also help control your body temperature, heart rate, cholesterol levels, and metabolism. Importantly, your metabolism is the process of how your body takes food and turns it into the energy you use. If your thyroid is not working efficiently, you undoubtedly will suffer from tiredness, low energy levels, and feelings of depression
