Likelihood of Occurrence

Pharmacist Analysis
Ashwagandha seems to have a relatively mild anti-diabetic effect via several different mechanisms.
Studies in both people and animals have shown that ashwagandha extract can lower blood sugar levels by boosting the uptake of glucose into fat and muscle cells. The active components believed to be responsible for these effects include withaferin A and withanolide A and thus, higher content of each has been related to a stronger anti-diabetic effect.
Studies have also found that withanolides may block a digestive enzyme called alpha-glucosidase, which could slow the breakdown of carbohydrates.
This interaction between ashwagandha and other medications used for diabetes may actually have a positive outcome, as it may boost the blood sugar-lowering effect of other drugs. However, it's still important to keep an eye out for the possibility of low blood sugar levels, even though there haven't been any reports of this happening in clinical studies.
As always, be sure you let your doctor know about all the medications you are taking so you can be appropriately monitored.
