Hyperhidrosis is characterized by excessive sweating especially at the palms of the hands and soles of the feet. Which of the following could cause this disorder? Choose 1 answer: A Increased sweat at the base of hair follicles B Appcrine gland activation with puberty C Higher density of holocrine glands D Increased stimulation of merocrine glands

## Step 1<br />Hyperhidrosis is a condition characterized by excessive sweating, particularly at the palms of the hands and soles of the feet. The question asks us to identify the cause of this disorder from the given options.<br /><br />## Step 2<br />Let's analyze each option:<br /><br />### A. Increased sweat at the base of hair follicles<br />This option is not correct. The sweat produced at the base of hair follicles is typically associated with eccrine sweat glands, which are not the primary glands involved in hyperhidrosis.<br /><br />### B. Apocrine gland activation with puberty<br />This option is also incorrect. Apocrine glands are activated during puberty and produce a thicker, milky sweat. While they are present in the palms and soles, they are not the primary cause of hyperhidrosis.<br /><br />### C. Higher density of holocrine glands<br />This option is incorrect as well. Holocrine glands, such as sebaceous glands, are not primarily involved in sweat production. They are more associated with the production of sebum, an oily substance.<br /><br />### D. Increased stimulation of merocrine glands<br />This option is correct. Merocrine glands, also known as eccrine glands, are the primary sweat glands involved in hyperhidrosis. They are responsible for the majority of our daily sweat production and are particularly active during periods of emotional stress or high environmental temperatures.
