“Being tired” is a non-specific symptom that could mean many things:
- A lack of sleep. A day nap might fix this.
- You can order blood tests like T3, T4 and TSH to diagnose this. Thyroid hormone replacements will help to rectify the tiredness of this condition.
- Fibromyalgia, in which case you would need a referral to a rheumatologist.
- Low cortisol blood levels are found with adrenal fatigue or Addison’s disease. Adrenal Gland Hormones – Net Health Book
- Low red cell blood counts account for tiredness. Anemia Due To Blood Loss – Net Health Book
- Depression: Depression – Net Health BookHere the tiredness comes from mental changes with depression.
- Cancer can be an insidious disease, which sometimes is difficult to diagnose in the early stages. Here are some comments from the Canadian Cancer Society about fatigue in cancer patients: Fatigue – Canadian Cancer Society.
“Is being tired all the time due to old age, lack of vitamins & nutrients, or a combination of both?” There are many more causes of tiredness than I listed. A physician needs to examine the patient, take a good history and do some blood tests as well as possibly some scans (ultrasound, MRI scan etc.) to diagnose and treat the underlying condition. Old age can sometimes be the cause of tiredness. This person might benefit from 400 mg of CoQ10, a simple supplement that stimulates mitochondria to make more energy. A lack of vitamin B12 in older age leads to pernicious anemia, which responds rapidly to vitamin B12 injections.
