Diseases, Illnesses & Ailments Starting from Letter H

  1. Hepatomegaly
    Hepatomegaly is the condition of having an abnormally enlarged liver. [read more]

  2. Hepatorenal syndrome
    Hepatorenal syndrome (HRS) refers to acute renal failure that arises in the setting of cirrhosis or fulminant liver failure associated with portal hypertension, generally in the absence of other disease of the kidney. [read more]

  3. Hereditary amyloidosis
    In medicine, amyloidosis refers to a group of conditions in which amyloid proteins are abnormally deposited in organs and/or tissues, causing disease. A protein is amyloid if, because of an alteration in its secondary structure, it takes on a particular insoluble form, called the beta-pleated sheet. [read more]

  4. Hereditary angioedema
    Angioedema, also known as Quincke's edema, is the rapid swelling (or edema) of the skin, mucosa and submucosal tissues. Aside from the common form, mediated by allergy, it has been reported as a side effect of some medications, specifically ACE inhibitors. [read more]

  5. Hereditary ataxia
    The hereditary ataxias are a group of genetic disorders marked by slowly progressive incoordination of gait and often associated with poor coordination of hands, speech, and eye movements. Frequently, atrophy of the cerebellum arises. The hereditary ataxias are grouped by mode of inheritance and causative gene or chromosomal locus. [read more]

  6. Hereditary ceroid lipofuscinosis
    Hereditary ceroid lipofuscinosis (also known as Batten Disease or NCL) is a fatal, inherited disorder of the nervous system that starts in childhood. In some cases, the early signs are subtle, taking the form of personality and behavior changes, clumsiness, slow learning, or stumbling. [read more]

  7. Hereditary coproporphyria
    Hereditary coproporphyria (HCP) is a form of hepatic porphyria linked with a deficiency of the enzyme coproporphyrinogen III oxidase. [read more]

  8. Hereditary deafness
    Hereditary deafness is hearing loss that is passed down from parents to their children. This type of hearing loss may be inherited from one or both parents who may or may not possess a loss of hearing themselves. [read more]

  9. Hereditary Deafness Retinitis Pigmentosa
    Hereditary deafness-retinitis pigmentosa, also known as Usher syndrome, is a rare genetic disorder that features deafness and progressive loss of vision. This condition is due to the impairment of the auditory nerves to send sensory input to the brain. Hereditary deafness-retinitis pigmentosa has three types, and is categorized as an autosomal recessive disorder. [read more]

  10. Hereditary elliptocytosis
    Hereditary elliptocytosis is a blood disorder in which a large proportion of the sufferer's erythrocytes (i.e. red blood cells) are elliptical instead of being biconcave disc-shaped. The disorder comes before haemolytic anaemia. [read more]

  11. Hereditary fructose intolerance
    Hereditary fructose intolerance (HFI) or fructose poisoning is a hereditary condition that results from a deficiency of liver enzymes that metabolise fructose. This is also known as hereditary fructosemia, or fructose in the blood. [read more]

  12. Hereditary hemochromatosis
    Hereditary hemochromatosis is a genetic disease that results to the body absorbing and storing too much iron. The condition gets its name from "hemo" for blood and "chroma" for color, alluding to the characteristic bronze skin tone that iron overload can cause. Someone with hereditary hemochromatosis who has never taken an iron supplement could find out in later years that iron overload is leading to serious health problems. [read more]

  13. Hereditary hemorrhagic telangiectasia
    Hereditary hemorrhagic telangiectasia (HHT) is a disorder that leads to the development of multiple abnormalities in the blood vessels. [read more]

  14. Hereditary non-spherocytic hemolytic anemia
    Hereditary nonspherocytic hemolytic anemia is a term used to describe a group of rare, genetically transmitted blood disorders marked by the premature destruction of red blood cells (erythrocytes or RBCs). If the red blood cells cannot be replaced faster than they destroy themselves, anemia results. [read more]

  15. Hereditary pancreatitis
    Hereditary pancreatitis is a genetic disease affecting the production of enzymes in the pancreas. In the pancreas, a genetic mutation causes the enzyme cationin trypsinogen to be made in a way which leaves it resistant to inactivation through autolysis. Normally this autolysis mechanism prevents trypsinogen from being activated inside the pancreas. However, when the abnormal trypsinogen is activated, it results to a chain reaction where all the trypsinogen in the pancreas is activated, effectively digesting the pancreas from the inside. [read more]

  16. Hereditary Sensory Motor Neuropathy
    Hereditary sensory motor neuropathy is a genetic disorder that leads to nerve damage. Also known as Charcot-Marie Tooth disease, it usually triggers the legs, hands, arms and feet. It also causes reduced sensation, but it is not life-threatening. [read more]

  17. Hereditary spastic paraplegia
    Hereditary spastic paraplegia (HSP), also known as familial spastic paraparesis (FSP), refers to a group of inherited disorders that are marked by progressive weakness and stiffness of the legs [read more]

  18. Hereditary spherocytosis
    Hereditary spherocytosis is a genetically-transmitted form of spherocytosis, an auto-hemolytic anemia marked by the production of red blood cells that are sphere-shaped rather than donut-shaped, and therefore more prone to hemolysis. [read more]

  19. Heritable Disorders Of Connective Tissue
    Heritable disorders of connective tissue are muscular diseases that cause the connective tissues to degenerate. Connective tissues such as collagen and elastin are important as they link the different organs together, and deterioration of these tissues can lead to muscular problems, weakness and paralysis. Among the kinds of hereditary connective tissue disorders are the Marfan syndrome, Ehlers-Danlos syndrome, and osteogenesis imperfecta, or the brittle bone disease. [read more]

  20. Hermansky-Pudlak Syndrome
    Hermansky-Pudlak Syndrome (HPS) is an inherited disease which leads to oculocutaneous albinism (decreased pigmentation), bleeding problems due to a platelet abnormality (platelet storage pool defect), and storage of an abnormal fat-protein compound (lysosomal accumulation of ceroid lipofuscin). [read more]
