What term describes an acute inflammatory disorder of the sweat glands due to excessive heat exposure?

1. Miliaria rubra

2. Heat rash

3. Cholinergic urticaria

4. Hyperhidrosis

The correct answer is: Miliaria rubra

The term that accurately describes an acute inflammatory disorder of the sweat glands resulting from excessive heat exposure is miliaria rubra, often referred to as heat rash. This condition occurs when sweat glands become blocked and sweat is trapped beneath the skin, leading to redness, itching, and discomfort. Miliaria rubra typically arises in hot and humid conditions, making it particularly prevalent in situations of increased perspiration, such as high temperatures or heavy exercise. Heat rash is a common colloquial term used to describe miliaria rubra but is not a precise medical term. Cholinergic urticaria refers to a different condition characterized by hives triggered by an increase in body temperature, often due to exercise or heat. Hyperhidrosis refers to a medical condition of excessive sweating that is not limited to inflammation or specific exposure to heat, but rather pertains to overactivity of the sweat glands in general. Thus, miliaria rubra is the most clinically accurate term to describe the specific condition indicated in the question.
