What Is The Treatment For Constipation?

I m 21 yrs old and i have been facing this constipation problem since my childhood and i never i took care of it nor considered it serious. Slowly the things got worse. I used to feel always lazy, not concentrated to do any work,simply get frustrated and my body not co-operating me to do any work. I don t feel hungry at regular times and just simply eat because I have to eat.When I go to classes I just simply sit and drown into sleep.I feel inactive and uninterested to answer to any questions in the class though i knew them. At times I ll be good at doing things when I attend the calls regularly in morning. But this lasts only for few days again the same thing repeats.as a result of this improper metabolisim my belly, thighs and hip got fatted. I appear short with thin hands but other parts of me are awkward due to this constipation problem. I have consulted the doctor once regarding this problem , but the doctor instead of under standing my problem started laughing as though I was cracking jokes in front of him.I was really humiliated and felt depressed and never went to any doctor for the sake of this. Another thing is I drink 2-3 glasses of water daily in the morning and as I stay in hostel, I can t afford a proper diet. The food I get is rice and dal, my mrng break fast starts with rice receips and the dinner also ends with the same along with dal. so, I therefore kindly request you to cosider my problem and recommend me the tablets that are necessary and thank you in advance
