Sudden decrease on my weight

Can you suggest me that???
What might be the causes for this???
Help me, please

you should go see a doctor.. sudden weight loss can be serious. good luck

I too suffered it ... but that was due to erratic work schedule !! am now better ...

If you have reduced weight PLUS some health problem -- like pain in the abdomen or loss of apetitie or increased fatigue etc...it could be a problem.
