Arteriosclerosis is described as a cardiac disorder that results in hardening of the arterial walls. This can affect elasticity, and in turn blood circulation and blood pressure. The illness is different from Atherosclerosis, as Atherosclerosis is a buildup of debris in the artery (Plaques forming from fat deposits, platelets, clotting, etc..) Many times though Arteriosclerosis and Atherosclerosis work in tandem to worsen cardiovascular health, greatly increasing chances of Aneurysms, Emboli (Traveling clots), or Thrombi (stationary clots)
Colon is the large intestine which absorbs water and minerals from the ingested food and removes the undigested food through rectum. Diverculum is a small tissue sac formed inside the colon. The condition of having Divercula is called as Diverticulosis.
Diverticulosis causes abdominal pain, constipation, diarrhoea and sometimes bleeding in most people. Some people do not even get any symptoms of having it. The presence of divercula is observed through colonoscopy. If Jessica doesn't have any of the symptoms, then she should not worry about it.
If the doctor prescribes her to get colonoscopy done then she can be positive and hope for the best. Having a medical knowledge can help one in any of the circumstances be it common cold, fever, a disease or if the person has met with an accident.
