Hallo I am on a water pill now for 3 months bud now I get cramps can it be the los of water? And what can I do to get rut of the cramps? Thank you!

Maybe. Diuretics can cause cramps but your's is a very mild one. I presume it's hot in s. Africa this time of year - are you dehydrated? Do you need the diuretic during your summer? If it's for bp, perhaps a different medicine could be used. Tonic water and muscle stretching exercises can help cramps in general.
