chronic mountain sickness

The slow onset of symptoms in people who reside at high altitude for several years. The symptoms include apathy, fatigue, and headache. Laboratory studies often reveal hypoxia and polycythemia.

morning sickness

The nausea and vomiting that affects many women during the first few months of pregnancy. The condition typically starts about 4 to 6 weeks after conception, peaks in incidence and severity between 8 and 11 weeks, and subsides spontaneously between 12 and 16 weeks of gestation. It occurs in 50% to 88% of pregnancies and is the most common complaint in the first trimester.
SYN: SEE: nausea and vomiting of pregnancy

SYMPTOMS
Complaints vary from mild nausea on arising to severe intermittent nausea and vomiting throughout the day. The woman may experience headache, vertigo, and exhaustion, as well. Severe, persistent vomiting with retching between meals should be reported and investigated.
SEE: hyperemesis gravidarum

PATIENT CARE
In many cases, dietary management will improve symptoms. This may include, for example, avoiding stimuli that contribute to nausea, drinking or eating colder liquids or foods, taking smaller portions, or frequent sips of fluid. Ginger-containing fluids and foods or vitamin supplementation with pyridoxine can be beneficial for some pregnant women. When vomiting causes dehydration or electrolyte imbalances, intravenous fluids should be provided, often with medications given judiciously to control nausea and vomiting.

The use of any drug during pregnancy should be carefully evaluated before administration to avoid possible damage to the fetus.

motion sickness

A syndrome, marked primarily by nausea and/or vomiting, due to a conflict between the true vertical axis and the subjective or perceived vertical axis. Motion sickness is a common illness experienced by car, boat, plane, or space travelers. It is also sometimes felt during motion picture viewing. Susceptibility to motion sickness is greatest between the ages of 2 and 12; it lessens with age but can be provoked in most people if the inciting stimulus is strong enough.

TREATMENT
Antimotion sickness medications include diazepam, diphenhydramine, meclizine, and scopolamine. Some patients with motion sickness benefit by eating small quantities of food when they begin to feel ill.

serum sickness

A delayed hypersensitivity response consisting of rash, fever, and joint pains, typically occurring 7 to 14 days after exposure to a foreign antigen. The disease is characterized by the development of immune complexes between the patient’s immunoglobulins and the foreign antigen. If these are not cleared by macrophages, they may deposit in blood vessels, joints, and other organs, and activate complement. Common causes include exposure to immune-modulating drugs, some anti-globulins, and anti-venoms. A similar syndrome without immune complex formation can occur after administration of antibiotics, such as penicillins or cephalosporins, and rarely, some other drugs or viral infections. Treatment consists of stopping any drug that causes the syndrome, and giving aspirin or antihistamines (for mild cases) or glucocorticoids (for severe disease).
