Diseases, Illnesses & Ailments Starting from Letter A


  1. Allergic bronchopulmonary aspergillus
    Allergic bronchopulmonary aspergillus is a serious respiratory disorder that is characterized by the allergic reaction of the lungs to a certain type of fungus. This disease occurs mostly in individuals that has cystic fibrosis and asthma, triggering cough, wheezing and in some cases accompanies by fever. If left untreated, this disorder may cause serious lung damage. [read more]

  2. Allergic Cascade
    Allergic cascade is the medical term used to describe a sequence of chemical release that takes place in response to allergens. [read more]

  3. Allergic Rhinitis
    Allergic Rhinitis Also called Hay Fever. Defined as an inflammation of the nasal passages, usually presents with watery nasal discharge and itching of the nose and eyes. [read more]

  4. Alopecia
    Alopecia is the medical description for loss of hair from the body or head that sometimes lead to baldness, often unwelcome and unwanted. However, there are some individuals who display some psychological compulsion to forcibly pull out own hair. In some cases, hair loss can also present an underlying case for other medical concern such as iron deficiency. [read more]

  5. Alopecia areata
    Alopecia areata is a medical condition that affects humans, characterized by excessive loss of hair in certain areas of the body, typically the scalp. This disease is often referred to as spot baldness since the initial stage causes the formation of bald spots that gradually spread through all areas of the scalp. [read more]

  6. Alopecia Totalis
    Alopecia totalis means “loss of all hair in the head” that affects men, women and children. While the causes of alopecia totalis is still unclear, research has confirmed that this condition is an autoimmune disorder, wherein an organism fails to recognize its own parts as “self” and results in a negative response against its own tissues and cells. [read more]

  7. Alopecia universalis
    Alopecia Universalis, also known as “Alopecia areata universalis” is a condition that involves rapid loss of all hair, including eyelashes and eyebrows. Alopecia universalis is the most serious type of alopecia areata, affecting only 1 person in 100,000. [read more]

  8. Alopecia, Female Pattern
    The medical term for hair loss is called alopecia. Female alopecia is often characterized as being distressing and common. Caused by hormones, genes and aging, female pattern baldness involves a typical patter of loss of hair in women. [read more]

  9. Alopecia, Male Pattern
    Androgenetic alopecia or the male pattern baldness is the patterned balding of a man. One should note that the condition is not a medical disorder although it may affect both the appearance and self-esteem of some men. [read more]

  10. Alpers disease
    Named after Bernard Jacob Alpers, Alper's disease is a progressive degenerative disease that affects the central nervous system. Also called progressive sclerosing polidystrophy, progressive infantile poliodystrophy, progressive neuronal degeneration of childhood and Alpers' syndrome, this autosomal recessive disorder only occurs in infants and children, sometimes in siblings. [read more]

  11. Alpha 1-antitrypsin deficiency
    Alpha 1-antitrypsin deficiency, also known simply as Alpha-1 or A1AD, is a genetic disorder caused by the defective production of “alpha 1-antitrypsin”. When this happens, the blood and lungs receives insufficient amounts of A1AT while the liver cells receive excess amounts of A1AT proteins. Serious cases of Alpha-1 cause emphysema in most patients with this condition. Children and adults may experience liver diseases. Treatments of this disease include intravenous A1AT protein infusions, liver or lung transplants and avoidance of dangerous inhalants. People of Iberian, Saudi Arabian and northern European ancestry are more at risk of having A1AD. [read more]

  12. Alpha-mannosidosis
    Alpha-mannosidosis is an “autosomal recessive metabolic disorder” that leads to physical and mental deterioration. When the a-mannosidase enzyme becomes defective, it causes impaired cell function and sugar buildup. Since this enzyme normally helps in breaking down complex sugars, absence of this functional enzyme may lead to death on children caused by deterioration of the central nervous system. [read more]

  13. Alpha-thalassemia
    In this condition, “a thalassemias” involve genes HBA1 and HBA2, which occurs due to Mendelian inheritance in a recessive fashion. Alpha-thalassemia is also connected to the deletion of 16p chromosome. Alpha-thalassemia results in a decrease in alpha-globin production that causes a decrease in the production of alpha-globin chains. As a result, an excess of beta chains occur in adults, while an excess of gamma chains occur in newborns. [read more]

  14. Alport syndrome
    Alport syndrome, which first occurred in a British family and identified by Dr. Cecil Alport in 1927, is a genetic disorder characterized by end-stage kidney disease, hearing loss and glomerulonephritis. Hematuria or the presence of blood in urine always occurs in patients with this condition. Some also develop eye problems. [read more]

  15. Alstrom syndrome
    Alstrom syndrome is a very rare genetic disorder – one of the rarest in the world, existing in only 266 reported cases in medical books and only 411 patients in 42 countries. First described by Carl Henry Alstrom in 1959, this condition is usually mistaken with Bardet-Biedl syndrome, which has resembling symptoms. However, the Bardet-Biedl syndrome usually have later onset with its symptoms. [read more]

  16. Alternating hemiplegia of childhood
    Alternating hemiplegia of childhoon or “AHC” is a rare genetic disease that causes progressive mental retardation and intermittent paralysis, which starts during childhood. [read more]

  17. Altitude Illness
    Alternative names for Altitude Illness are the ff: High altitude cerebral edema; High altitude pulmonary edema; Mountain sickness; acute mountain sickness. Altitude Illness is a sickness that can influence mountain climbers, hikers, skiers, or travelers who climb very fast; usually encountered when reaching high elevation in a very rapid manner. [read more]

  18. Altophobia
    Altophobia, or acrophobia, is a person's fear of heights. This fear can be very dangerous especially to those who are exploring high elevations; they may suddenly experience panic attack while going higher above the ground causing their heart to palpitate and lead to serious complications. [read more]

  19. Alveolar Capillary Dysplasia
    (ACD) is defined as a lethal evolving anomaly of the pulmonary vasculature. It is normally illustrated as the miscarriage of the normal air-blood diffusion barrier in the newborn lung. It is usually supplementary with the misalignment of the pulmonary veins. [read more]

  20. Alveolar Hydatid Disease
    Alveolar Hydatid Disease is a rare medical condition where there is a multi-organ infection caused by the larval stage of a Echinococcus multilocularis, tapeworm that is usually microscopic and is usually found in foxes, coyote, dogs and cats. When affecting human, the tapeworm thrive on the lungs, brain and organs of the body. [read more]
