High Blood Pressure/Hypertension:
High Cholesterol: High levels of blood cholesterol, triglycerides, or other lipids.
Hip cancer: The presence of tumour growth in the bone of the hip, whether due to primary malignancies e.g. leukaemic or myeloma infiltration of the bone marrow, or due to secondary metastases from another site e.g. lung or breast; cancer affecting bone of hip likely to affect other bones e.g. vertebra, ribs
Histoplasmosis: Lung infection from fungus Histoplasma capsulatum
Hydronephrosis congenital: A rare kidney disorder that is present at birth and involves enlargement of the part of the ureter closest to the kidney due to obstruction of the flow of urine out of the kidney. The severity of the condition is determined by the degree of obstruction.
Hyperadrenalism: Excessive levels of adrenal hormones in the body. Symptoms depend on which hormone is involved and the degree of involvement. Adrenal hormones are aldosterone, corticosteroids, androgenic steroids, epinephrine and norepinephrine.
Hyperaldosteronism-induced hypertension: Hyperaldosteronism -induced hypertension is high blood pressure caused by excessive production of a hormone called aldosterone by the adrenal glands. The high blood pressure often responds poorly to the usual medications. Death can result in severe cases.
Hyperchromic Anemia: Hyperchromic anemia is a blood disorder characterized by red blood cells which contain abnormally high amounts of haemoglobin as well as a reduced number of red blood cells. This anomaly is often caused by such things as Vitamin B12 deficiency and pernicious anemia.
Hyperlipoproteinemia type 3: A rare genetic disorder characterized by the body's impaired ability to break down certain lipids (triglycerides) which results in their buildup in the blood.
Hypertension: High blood pressure
Hypertension due to bilateral renal artery stenosis: Hypertension due to bilateral renal artery stenosis is high blood pressure resulting from narrowing kidney blood vessels which prevents the blood from flowing through the kidneys properly.
Hypertension due to coarctation of the aorta: Hypertension due to coarctation of the aorta is high blood pressure resulting from a birth defect where a heart blood vessel called the aorta is abnormally narrowed. The high blood pressure tends to affect mainly the upper part of the body. Babies and very young children tend to have more severe symptoms as the degree of narrowing tends to be greater than in older children or adults.
Hypertension in children one to ten years: Hypertension in children one to ten years refers to a child between the ages of one to ten years who has an abnormal elevation in blood pressure.
Hypertension, Essential: Essential hypertension is a type of hypertension that has no detectable cause. Patients have an increased blood pressure for no apparent reason. Most cases of hypertension are of this form.
Hypertension, Essential, Susceptibility to: Essential hypertension is a type of hypertension that has no detectable cause. Patients have an increased blood pressure for no apparent reason. Most cases of hypertension are of this form. Researchers have identified a number of genes linked to an increased susceptibility of developing hypertension.
Hypertension, Essential, Susceptibility to, 1: Essential hypertension is a type of hypertension that has no detectable cause. Patients have an increased blood pressure for no apparent reason. Most cases of hypertension are of this form. Researchers have identified a number of genes linked to an increased susceptibility of developing hypertension. Type 1 is linked to a defect on chromosome 17q.
Hypertension, Essential, Susceptibility to, 2: Essential hypertension is a type of hypertension that has no detectable cause. Patients have an increased blood pressure for no apparent reason. Most cases of hypertension are of this form. Researchers have identified a number of genes linked to an increased susceptibility of developing hypertension. Type 2 is linked to a defect on chromosome 15q.
Hypertension, Essential, Susceptibility to, 3: Essential hypertension is a type of hypertension that has no detectable cause. Patients have an increased blood pressure for no apparent reason. Most cases of hypertension are of this form. Researchers have identified a number of genes linked to an increased susceptibility of developing hypertension. Type 3 is linked to a defect on chromosome 2p25-p24.
Hypertension, Essential, Susceptibility to, 4: Essential hypertension is a type of hypertension that has no detectable cause. Patients have an increased blood pressure for no apparent reason. Most cases of hypertension are of this form. Researchers have identified a number of genes linked to an increased susceptibility of developing hypertension. Type 4 is linked to a defect on chromosome 12p12.2-p12.1.
Hypertension, Essential, Susceptibility to, 5: Essential hypertension is a type of hypertension that has no detectable cause. Patients have an increased blood pressure for no apparent reason. Most cases of hypertension are of this form. Researchers have identified a number of genes linked to an increased susceptibility of developing hypertension. Type 5 is linked to a defect on chromosome 20q11-q13.
Hypertension, Essential, Susceptibility to, 6: Essential hypertension is a type of hypertension that has no detectable cause. Patients have an increased blood pressure for no apparent reason. Most cases of hypertension are of this form. Researchers have identified a number of genes linked to an increased susceptibility of developing hypertension. Type 6 is linked to a defect on chromosome 5p13-q12.
Hypertension, Essential, Susceptibility to, 7: Essential hypertension is a type of hypertension that has no detectable cause. Patients have an increased blood pressure for no apparent reason. Most cases of hypertension are of this form. Researchers have identified a number of genes linked to an increased susceptibility of developing hypertension. Type 7 is linked to a defect on chromosome 3p14.1-q12.3.
Hypertension, Essential, Susceptibility to, 8: Essential hypertension is a type of hypertension that has no detectable cause. Patients have an increased blood pressure for no apparent reason. Most cases of hypertension are of this form. Researchers have identified a number of genes linked to an increased susceptibility of developing hypertension. Type 8 is linked to a defect on chromosome 18q21.2.
Hypertensive heart disease: Heart disease that is caused by hypertension
Hypertrophic cardiomyopathy: Heart damage from thickened heart walls.
