Hypertension

"Hypertension is abnormally high blood pressure in the arteries, which are the blood vessels that carry blood from the heart to the rest of the body. " Blood pressure is the product of the blood pushing against the artery walls, and it is measured in units called millimeters of mercury. The top number in a blood pressure survey is the pressure when the heart pumps, while the bottom number is the pressure between heart beats. A normal blood pressure reading in adults is 120/80 mmHg. When the measurement is 130/80 mmHg or higher, blood pressure is considered high. Hypertension has no signs, and many affected people are unaware they have the disorder. To pump blood through the body, the heart and arteries must function harder than normal when blood pressure rises. Heart disease is caused by extra work and a lack of oxygen. In addition, heart artery damage increases the risk of blood clots blocking the flow of blood to the heart, causing a heart attack, or to the brain, causing a ischemic stroke. When a damaged blood vessel in the brain bursts, a hemorrhagic stroke may occur. Vision loss can result in vision loss if there are blood arteries in the eyes.

Preeclampsia

"Preeeclampsia is a complication of pregnancy in which affected women have elevated blood pressure, but urine samples can also have abnormally high amounts of protein. " Many women with mild preeclampsia do not feel ill, and the condition is often detected as a result of blood pressure and urine testing in their doctor's office. Preeclampsia can include excessive swelling of the face and hands, as well as a weight gain of more than 5 pounds in a week due to fluid retention, in addition to hypertension and proteinuria. Affected women may also experience headaches, dizziness, thirst, shortness of breath, a decrease in urinary, upper abdominal pain, and nausea or vomiting. Preeclampsia symptoms in some cases are gone within a few days after the baby is born. Extremely elevated blood pressure in the mother can lead to bleeding in the brain. Epilepsy may also be triggered by elevated blood pressure on the brain. Eclampsia is present in about 1 in every 200 women with untreated preeclampsia. Eclampsia can also develop without obvious signs of preeclampsia. Between ten and twenty percent of women with severe preeclampsia experience another potentially life-threatening disorder called HELLP syndrome. Infants who were delivered early due to preeclampsia may have respiratory difficulties as a result of underdeveloped lungs, such as breathing difficulties. Women with preeclampsia have about twice the lifetime risk of heart disease and stroke than do women in the general population.

Liddle syndrome

"Liddle syndrome is an inherited condition of elevated blood pressure. " Some people with Liddle syndrome have no additional signs or symptoms, particularly in childhood. Poor potassium levels in the blood can cause hypertension in addition to hypertension. Deficiency of potassium can also raise the pH of the blood, a condition that is also known as metabolic alkalosis. ".

Pulmonary arterial hypertension

"Pulmonary arterial hypertension is a progressive disorder characterized by persistently elevated blood pressure in the pulmonary artery, the blood vessel that transports blood from the heart to the lungs. " Pulmonary arterial hypertension is one of several disorders linked to pulmonary hypertension. To combat the increased resistance, blood pressure rises in the pulmonary artery and in the right ventricle of the heart, which is the chamber that pumps blood into the pulmonary artery. pulmonary arterial hypertension signs and symptoms develop as a result of elevated blood pressure that can't quite overcome the rising resistance.

Multiple endocrine neoplasia

"Multiple endocrine neoplasia is a group of disorders that affect the body's network of hormone-producing glands, referred to as the endocrine system. " Multiple endocrine glands are most typical of endocrine gland tumors in at least two endocrine glands, although tumors can also develop in other organs and tissues. If the tumors become cancerous, the disease can be life-threatening. Multiple endocrine neoplasia types 1, type 2, and type 4 are the most common types of multiple endocrine neoplasia. Multiple endocrine neoplasias are associated with several species of tumors. Tumors in these glands can cause hormone overproduction of hormones. Overactivity of the parathyroid glands is the most significant warning of multiple endocrine neoplasia type 1 (Figure 1). Medullary thyroid carcinoma is the most common symptom of multiple endocrine neoplasia type 2 in the United States. Pheochromocytoma, an adrenal gland tumor that can cause dangerously high blood pressure, is common among those with this disorder. Multiple endocrine tumors type 2A, type 2B, and familial medullary thyroid carcinoma are divided into three subtypes: type 2A, type 2B, and familial medullary thyroid carcinoma. The only characteristic of FMTC is a medullary thyroid carcinoma; for example, hyperparathyroidism occurs only in type 2A; however, medullary thyroid carcinoma is the only sign and cause of specific tumors. Multiple endocrine neoplasia type 2 signs and symptoms are relatively similar within any one family. Multiple endocrine neoplasia type 4 has signs and symptoms similar to those of type 1, but it is caused by mutations in a different gene. ".
