Take some precausation and cure your disease.
1-Donot take depression
2-If u have problem after taking milk so avoid the milk and take Mattha mixed with Hingwastak churana twice glass in a day.
3-Donot take food in excess amount and in take in limited amount.
4-U can take alovera juice 20ml in a day.
5-Take cooked food and avoid un cooked food like sprouts,prunes,legumes,beans,apples.
6-identify the precipitating food and avoid it.
