Low blood pressure, also referred to as hypotension, is blood pressure that is so low that it causes symptoms or signs due to the low flow of blood through the arteries and veins. Some of the symptoms of low blood pressure include light-headedness, dizziness, or even fainting if not enough blood is getting to the brain. Diseases and medications can also cause low blood pressure. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidneys; the organs do not function normally and may be permanently damaged.
Anemia is the condition of having less than the normal number of red blood cells or less than the normal quantity of hemoglobin in the blood. The oxygen-carrying capacity of the blood is, therefore, decreased.
Gout is a condition that results from crystals of uric acid depositing in tissues of the body. Gout is a condition that can lead to abnormally elevated levels of uric acid in the
blood, recurring attacks of joint inflammation (arthritis), deposits of
hard lumps of uric acid in and around the joints, and decreased kidney
function and kidney stones.
Dehydration is the excessive loss of body water. There are a number of causes of dehydration including heat exposure, prolonged vigorous exercise, and some diseases of the gastrointestinal tract. The best way to treat dehydration is to prevent it from occurring.
Cirrhosis of the liver refers to a disease in which normal liver cells are replaced by scar tissue caused by alcohol and viral hepatitis B and C. This disease leads to abnormalities in the liver's ability to handle toxins and blood flow, causing internal bleeding, kidney failure, mental confusion, coma, body fluid accumulation, and frequent infections. Symptoms include yellowing of the skin, itching, and fatigue.
Systemic lupus erythematosus is a condition characterized by chronic inflammation of body tissues caused by autoimmune disease. Lupus can cause disease of the skin, heart, lungs, kidneys, joints, and nervous
system. When only the skin is involved, the condition is called discoid lupus.
When internal organs are involved, the condition is called systemic lupus
erythematosus (SLE).
Hyperkalemia is an abnormally high level of potassium in the blood. Symptoms of hyperkalemia include nausea, fatigue, tingling sensations, or muscle weakness. Hyperkalemia may also cause no symptoms. Slow heartbeat and weak pulse are more serious symptoms. Causes of hyperkalemia include kidney dysfunction, medications, adrenal gland diseases, and potassium shifts. Treatment of hyperkalemia is dependant upon the cause.
Restless leg syndrome (RLS or restless legs syndrome) is a common cause for painful legs that typically eases with motion, and becomes worse and more noticeable at rest. This characteristic nighttime worsening can frequently lead to insomnia. Treatment of the symptoms of restless leg syndrome is generally with medication as well as treating any underlying condition causing restless leg syndrome.
Sepsis (blood poisoning) is a potentially deadly infection with signs and symptoms that include elevated heart rate, low or high temperature, rapid breathing and/or a white blood cell count that is too high or too low and has more than 10% band cells. Most cases of sepsis are caused by bacterial infections, and some cases are caused by fungal infections. Treatment requires hospitalization, IV antibiotics, and therapy to treat any organ dysfunction.
Hyponatremia is a condition where the level of sodium in the blood is low. Causes of hyponatremia can occur from excess fluid in the body, or a loss of sodium in body fluid. Some of the symptoms of hyponatremia include headache, muscle cramps or spasm, seizures, weakness and confusion. Treatment of hyponatremia depends on the cause.
Thrombocytopenia refers to a decreased number of platelets in the blood. There are many causes of thrombocytopenia such as decreased platelet production (viral infections for example rubella, mumps, chickenpox, hepatitis C, and HIV); increased platelet destruction or consumption (for example sulfonamide antibiotics, heparin, blood transfusions, and lupus); or increased splenic sequestration (enlarged spleen due to conditions for example liver disease, blood cancers, and more). Treatment of thrombocytopenia depends on the cause.
Malaria is an infectious disease transmitted by the bite of an infected Anopheles mosquito. Symptoms of malaria include chills, pain, fever, and sweating. Though mild cases of malaria can be treated with oral medication, severe cases require intravenous drug treatment and fluids.
Rhabdomyolysis is a rapid deterioration and destruction of skeletal muscle. Some of the causes of rhabdomyolysis include severe burns, muscle trauma, coma, seizures, electrolyte imbalance, medications (statins), viruses, bacteria. Treatment of rhabdomyolysis depends on the cause.
Vancomycin-resistant enterococci (VRE) infection is the most common type of infection acquired by patients while hospitalized. Patients at risk for VRE are those who are already ill, and hospitalized, including individuals with diabetes, elderly, ICU patients, kidney failure patients, or patients requiring catheters. Enterococci can survive for months in the digestive tract and female genital tract. Other risk factors for acquiring VRE include those how have been previously treated with vancomycin and combinations of other antibiotics. Treatment of VRE is generally with other antibiotics other than vancomycin. Prevention of VRE can be achieved by proper hand hygiene.
Encephalopathy means brain disease, damage, or malfunction. Causes of encephalopathy are varied and numerous. The main symptom of encephalopathy is an altered mental state. Other symptoms include lethargy, dementia, seizures, tremors, and coma. Treatment of encephalopathy depends on the type of encephalopathy (anoxia, diabetic, Hashimoto's, hepatic, hyper - hypotensive, infectious, metabolic, infections, uremic, or Wernicke's) are examples of types of encephalopathy.
Pleural effusion is an excess fluid between the two membranes that envelop the lungs. There are two classifications of causes of pleural effusion; transudate and exudate. The treatment of pleural effusion depends on the cause.
Pulmonary edema (swelling or fluid in the lungs) can either be caused by cardiogenic causes (congestive heart failure, heart attacks, abnormal heart valves) or noncardiogenic causes such as ARDS, kidney failure, high altitude, pneumothorax, pleural effusion, aspirin overdose, pulmonary embolism, and infections. The treatment of pulmonary edema depends on the cause of the condition.
Pulmonary hypertension is an abnormal elevation of the pressure in the pulmonary circulation caused by the constriction of the blood vessels that supply blood to the lungs. Shortness of breath and dizziness are symptoms of pulmonary hypertension. Treatment involves diuretics, blood thinners, calcium channel blockers, and using supplemental oxygen to increase blood oxygen levels.
Hydronephrosis is a condition in which the kidney swells, due to a backup of urine. Hydronephrosis generally occurs with another disease.Symptoms of hydronephrosis include nausea, vomiting, urinary tract infection, fever, painful urination, increased urinary frequency and urgency, flank pain, and swelling of the abdomen. Treatment of hydronephrosis depends on the cause.
Burns are categorized by severity as first, second, or third degree. First degree burns are similar to a painful sunburn. The damage is more severe with second degree burns, leading to blistering and more intense pain. The skin turns white and loses sensation with third degree burns. Burn treatment depends upon the location, total burn area, and intensity of the burn.
Pericarditis is the inflammation of the pericardial sac that surrounds the heart. The causes of pericarditis include injury from heart attack, heart surgery, trauma; viral or fungal infection, HIV, tumors, mixed connective tissue disease, metabolic disease, medication reactions, or idiopathic. Treatment for pericarditis is generally medication, however, sometimes surgery is necessary.
Gynecomastia, an enlargement of the gland tissue in the male breast is the caused by an imbalance of hormones. Certain medical conditions may also lead to gynecomastia such as cirrhosis, malnutrition, disorders of the male sex organs, kidney failure, thyroid disorders, and medications. Gynecomastia is generally treated with medication, and if necessary surgery.
Coma is the inability to waken or react to the surrounding environment. The Glasgow Coma Scale is frequently used to measure the depth of coma. Causes of coma include trauma, bleeding, edema, lack of oxygen, poisoning, or hypoglycemia. Prognosis for a patient in a coma depends on the cause of the coma.
Hypercalcemia is a condition in which calcium levels in the blood are elevated. Hypercalcemia is associated with other conditions such as hyperparathyroidism, lung cancer, breast cancer, kidney failure, and elevated levels of vitamin D. Symptoms of hypercalcemia include constipation, nausea, abdominal pain, kidney stones, to name a few. Treatment depends on the cause of hypercalcemia.
Renal artery stenosis is a narrowing of the diameter of the renal arteries. When the renal arteries narrow, the result is restricted blood flow to the kidneys, which may lead to impaired kidney function and high blood pressure (referred to as renovascular hypertension (RVHT). Renal artery stenosis can occur in one or both kidneys. The primary cause of renal artery stenosis is atherosclerosis. Risk factors for renal artery stenosis include high blood pressure, high cholesterol levels, age, cigarette smoking, and diabetes. Symptoms of renal artery stenosis include high blood pressure that does not respond to treatment, severe high blood pressure in individuals younger than 30 or greater than 50 years of age. Renal artery stenosis is diagnosed with imaging and functional tests. Treatment for renal artery stenosis include medication or surgery.
Polycystic kidney disease (PKD) is characterized by numerous cysts in the kidneys. Polycystic kidney disease is a genetic disorder. There are two major inherited forms of PKD, autosomal dominant PKD, and autosomal recessive PKD. Symptoms include headaches, urinary tract infections, blood in the urine, liver and pancreatic cysts, abnormal heart valves, high blood pressure, kidney stones, aneurysms, and diverticulosis. Diagnosis of PKD is generally with ultrasound, CT or MRI scan. There is no cure for PKD, so treatment of symptoms is usually the general protocol.
Diabetes insipidus is a condition in which the patient has frequent urination. Symptoms of diabetes insipidus include irritable, listless, fever, vomiting, or diarrhea due to the loss of large volumes of urine. There are three types of diabetes insipidus, central, nephrogenic, dipsogenic, and gestational. Treatment depends upon the type of diabetes insipidus.
High blood pressure can damage the kidneys and is one of the leading causes of kidney failure (end-stage renal kidney disease). Kidney damage, like hypertension, can be unnoticeable and detected only through medical tests. If you have kidney disease, you should control your blood pressure. Other treatment options include prescription medications.
Hiccups are a sudden, involuntary contraction of the diaphragm muscle. In general hiccups are just a temporary condition. Some of the causes of hiccups include certain medications, surgery, eating or drinking too much, spicy foods, diseases or conditions that irritate the nerves controlling the diaphragm, strokes, brain tumors, liver failure, and noxious fumes.
The skin has an important role to play in the fluid and temperature
regulation of the body. If enough skin area is injured, the ability to maintain
that control can be lost. The skin also acts as a protective barrier against the bacteria and
viruses that inhabit the world outside the body.
The anatomy of the skin is complex, and there are many structures within the
layers of the skin. There are three layers:
Epidermis, the outer layer of the skin
Dermis, made up of
collagen and elastic
fibers and where nerves, blood vessels, sweat glands, and hair follicles reside.
Hypodermis or subcutaneous tissue, where larger blood vessels and nerves
are located. This is the layer of tissue that is most important in temperature
regulation.
The amount of damage that a burn can cause depends upon its location, its
