This can be from several things. The list is too large to address without more information. Start recording how you diet makes you feel. See a doctor

If you are overweight, losing weight is imperative. Have a healthy diet, exercise 30 minutes/day, drink plenty of water daily so your urine is mostly colorless, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/. Get HPV vaccine.
