Is drinking water not allowed during fasting?

Muslims start fasting from the Sunrise until Sunset. Part of fasting is not to eat, drink, or have any sexual acts.

Alternate answer:

If you are fasting for another reason, it depends on what you are fasting from. You can be fasting from food but not necessarily drink (water, juice, etc.) If you are diabetic or suffer from some other illness, your body will need nutrients to replace the nutrients it is not getting during the period you are fasting.
