Pyloric stenosis is a rare disease that <u>affects infants</u>. It is characterized by the presence of <u>symptoms such as severe vomiting after feeding, weight loss, dehydration, constant hunger.</u> This happens because of a blockage that prevents the food from reaching the small intenstine due to an abnormal enlargement of the pylorus muscles.
Although the causes are still unknown,<u> researchers attribute this disease to genetic factors and</u>, possibly, to <u>environmental factors</u> as well. The treatment for pyloric stenosis usually involves surgery known as pyloromyotomy.
Blood pressure, exercise, emotional states (such as stress), body size, and caffeine all affect heart rate.
The total cholesterol level account for the low-density lipoprotein (LDL) and the high-density lipoprotein (HDL) and the triglycerides (fats and oils). LDL is also known as the 'bad' cholesterol because it caused blockage of arteries, while HDL are 'good' protein because they reduce the cholesterol build-up. The normal total cholesterol level is less than 200 mg/dL.
