Diffuse Muscle Weakness

Okay. But, it may still be worth reviewing the medicines you are taking to see if any may be to blame for your weakness.

Next, it's important to consider common hormonal or metabolic causes of muscle weakness. Examples include thyroid disorders, too much or too little calcium in the blood, and excessive cortisol (a hormone produced by the adrenal gland).

Do you have any of the following symptoms?

- Newly dry skin, a hoarse voice, intolerance of cold temperature, constipation (common symptoms of an underactive thyroid)

- Loss of appetite, nausea, constipation, frequent urination, increased thirst (common symptoms of high blood calcium)

- Muscle cramps, spasms or twitching, numbness, tingling, feeling irritable (common symptoms of low blood calcium)

Yes, I have noticed some of those symptoms!

No, none of that sounds familiar.
