Health concerns are usually classified as either acute or chronic. Acute illnesses often begin abruptly and last only a short time. Most people with an acute illness can expect to return to normal health. However, chronic diseases usually develop slowly, last a long time, and are often progressive and incurable.Chronic DiseasesChronic diseases, such as cardiovascular disease, cancer, and diabetes, are by far the leading cause of mortality in the world. Treatment includes medication and lifestyle changes such as diet and physical activity, and stress management. Cardiovascular diseases include coronary heart disease, hypertension, congenital heart disease, heart failure, etc. Once diagnosed with CVDs, patients are typically prescribed medication that will regulate cardiovascular functions and are usually taken daily for the rest of their life. Certain treatments are usually started right away if a heart attack is suspected, even before the diagnosis is confirmed. These include: oxygen, aspirin to prevent further blood clotting, nitroglycerin to reduce the workload on the heart, and treatment for chest pain.Cancer may affect people at all ages, even fetuses. The three most common types of cancer treatment are surgery, radiotherapy and chemotherapy, which aim at removing the cancer cells or destroying them in the body with medicines or other agents. Choice of treatment is influenced by several factors, including the specific characteristics of the cancer, the patient’s overall condition, and whether the goal of treatment is to cure the cancer, keep it from spreading, or relieve the symptoms.All forms of diabetes have been treatable since insulin became medically available in 1921, but there is no cure. The insulin injection is a basic treatment of type I diabetes. Type II is managed with a combination of dietary treatment, exercise, medications and insulin supplementation.Acute DiseaseTreatment for acute diseases usually involves medication of antibiotics, which have direct effects on inflammation. Pneumonia is a common illness which occurs in all age groups. Most cases of pneumonia can be treated without hospitalization. Typically, oral antibiotics, rest, fluids, and home care are sufficient for complete resolution. However, if the symptoms get worse, or complications occur, the person will often have to be hospitalized.Appendicitis is a condition characterized by inflammation of the appendix, which has been recognized as one of the most common causes of severe acute abdominal pain. Once a diagnosis of appendicitis is made, appendectomy is usually performed to remove the inflamed appendix. Antibiotics are always begun prior to surgery and as soon as appendicitis is suspected. Normally, the patient stays in the hospital for less than a week and can usually count on being back to a normal routine in three weeks. Once the useless appendix is removed, there is no danger of appendicitis recurring.（452 Words）
