Glossary for Sweat symptoms

Medical terms related to Sweat symptoms or mentioned in this section include:

The increased adrenal gland activity may be caused by an adrenal gland tumor or by excessive stimulation of the gland. Pituitary hormones stimulate adrenal gland activity.

Influenza A is a viral respiratory infection that can usually occurs in birds (especially poultry) but can be transmitted to humans and cause serious illness. The virus is contagious and can cause severe illness especially in patients who are very young or old or have some other medical condition as well. The severity of symptoms can vary but usually involves respiratory and constitutional (e.g. headache, aching muscles) symptoms. The influenza virus can mutate and produce different strains though the symptoms are the same. This frequent mutation means that people need regular vaccinations to ensure they are protected against new strains as they arise.

The second phase occurs one or two hours after envenomation where patients may recover somewhat but symptoms such as apnea and low blood pressure may develop.
• Furrier's lung: Inhalation of a dust from animal fur in an occupational setting can cause various lung symptoms. The severity of symptoms varies depending on the duration of the exposure. The lung symptoms result from the body's immune system reacting to exposure to the animal fur. Chronic exposure can lead to progressive lung symptoms which can gradually lead to symptoms such as weight loss and eventually lung scarring and possibly even respiratory failure in severe cases. Acute exposure results in symptoms such as fever, chills, shortness of breath and body aches.

It is characterized by the development of pustules in the flexural areas - the backs of the knees, the insides of the elbows, the armpits and the groin. These pustules continue to spread and soon they join to form lakes of pus. The pustules rupture easily and can become infected. This condition can be fatal if the patient gets dehydrated, or the infection spreads to the bloodstream. Generalized pustular psoriasis is often triggered by stopping topical or oral steroids.

Type II involves a problem with the processing of the growth hormone once it has been bound properly to the cell surface.
