Feeling weak can have various causes, ranging in severity from 'minor' to 'generally fatal'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose feeling weak, we could:
|Candida / Yeast||4%||Ruled out|
|Brain Tumor||2%||Ruled out|
|Low Carbohydrate Diet Consequences||0%||Ruled out|
|Pulmonary Fibrosis||0%||Ruled out|
Do you have a sensation of general weakness?
Possible responses:→ No / don't know
→ Occasional slight weakness but usually I'm fine
→ Frequent slight / occasional moderate weakness
→ Frequent moderate / occasional severe weakness
→ Severe weakness (almost) always, I can't function
The sensation of weakness, especially muscle weakness, may be due to the loss of muscle mass seen in andropause.
A loss of 4-5% of body weight of fluid decreases the capacity for hard muscular work by 20-30%.
Gradually increasing weakness is a sign of ketosis. The May 2004 Annals of Internal Medicine study showed that most of the Atkins Dieters suffered significantly more general weakness.
