Patient discussion about preventive

Q. Is there something I could do in order to prevent headaches? I have headaches often and somebody told me that there're steps to be taken in order to prevent headaches so often... Please help...

A. I just read your question on headaches. I have them occasionally as well. I don't like to take over the counter medication for headaches, so I rely on herbal supplemnts. You are ayoung man so I'm assuming you are very healthy. This herbal supplement shouldn't hurt you. It's very safe. I take at least 2 Valerian root capsules before going to bed. It relaxes your body abd it helps to eliminate headeaches.It also lowers the blood pressure which can sometimes cause headaches. Be sure you rule out any oraganic problems which can also cause headaches. You can find Valerian root at any health food/ organic markets.Also look at your diet MSG in food gives me headaches as well. I can always tell if it's present in foods right after I eat something processed. I stick with whole foods and I do yoga which helps as well. Let me know how if this works.

Q. How to prevent diverticulitis? I am a 43 year old man. I just had colonoscopy and my Doctor said I have diverticulosis and am at risk in developing diverticulitis. How can I prevent developing diverticulitis?

A. You have Diverticulosis, which means you have diverticulas (small pouches) on your digestive system. These diverticula are permanent and will not go away. No treatment has been found to prevent complications of diverticular disease. Diet high in fiber increases stool bulk and prevents constipation, and theoretically may help prevent further diverticular formation or worsening of the diverticular condition. Some doctors recommend avoiding nuts, corn, and seeds which can plug diverticular openings and cause diverticulitis. Whether avoidance of such foods is beneficial is unclear. If you develop unexplained fever, chills or abdominal pain, you should notify your doctor immediately since it could be a complication of diverticulitis.
