How should she be treated?
Gastroreflux disease (GERD). History should reveal a pattern of pain that follow meals and occurs at night or when prone. A physical exam can rule out little, but endoscopy can reveal abnormalities at the junction of the stomach and esophagus, such as a hiatal hernia. Treatment involves behavior changes such as taking smaller meals and avoiding food an hour before sleeping. Serious symptoms require surgical repair of the hiatal hernia.
The treatment for CHD depends on the severity of the disease and may include what?
Medications including blood pressure lowering agents, blood thinners, diuretics, nitrates such as nitroglycerin to stop chest pain, and lipid lowering medication. Lifestyle changes, such as a healthy, low-salt diet and exercise, are important to prevent further progression of the disease.
If needed what procedures are used to treat CHD?
Angioplasty with stent placement - Coronary artery bypass surgery.
What are the symptoms of CHD?
Chest pain, Angina Pectoris, (pain and pressure felt in the chest that results from ischemia), Palpitations or a sensation of a rapid pounding heartbeat, Dizziness, Fainting, Weakness upon exertion or at rest, and Shortness of breath, Myocardial infarction (cardiac arrest or a heart attach).
What are the risk factors for coronary heart disease?
Hypertension - Family history - Sedentary lifestyle - Overweight - High blood lipid levels - Atherosclerosis - Smoking.
What are the some symptoms of a myocardial infarction?
Crushing pain in the chest - Shortness of breath - Nausea - Pallor - Weakness - Faintness

T.W. experiences sharp pain in his upper right abdomen after eating a high-fat meal. Also he has noted that is feces are grayish white instead of brown. What disease is the likely cause of his symptoms? Explain why each of these symptoms occurs with this disease.
Cholelithiasis (gallstones). If bile flow to the small intestine is blocked, dietary fat remains undigested and is not absorbed from the intestines. As a result, fat appears in the feces. Follwoing a high-fat meal the gallbaldder secretes bile into the fmall intestine. Gallstones lodge in the bile ducts and cause pain in the upper right abdomen.
Explain how cirrhosis leads to each of this signs and symptoms: jaundice, malnutrition, hemorrhage, esophageal varices.
Normal liver tissue is replaced by scar or fat tissue, which does not function as normal liver tissue. The liver does not process hemoglobin that comes from dying erythrocytes and the orange and yellow colored breakdown products build up in blood, tinting the skin and eyes yellow. Normal liver tissue processes carbohytdrates and proteins and manufactures bile, which is used for fat absorption and the absorption of fat-soluble vitamins. The normal liver also manufactures clotting proteins. Finally, as blood flow through the liver is restricted by cirrhosis, abdominal and esophageal venous pressure increases, which leads to the distortion of the esophageal veins.
