Blocked sweat glands occur when the narrow ducts that transport sweat to the skin's surface become obstructed. This traps perspiration beneath the skin, often leading to irritation, bumps, or rashes. Common Causes Several factors can lead to a blockage:
Heavy antiperspirants, thick lotions, or deodorants that create a physical barrier can seal pores. blocked sweat gland
Blocked sweat glands encompass a spectrum from the trivial (miliaria crystallina) to the chronic and debilitating (Fox-Fordyce disease, widespread miliaria profunda). Eccrine duct obstruction is typically environmental and self-limiting, while apocrine duct obstruction (Fox-Fordyce) often requires long-term management. Hidradenitis suppurativa, despite historical classification as a sweat gland disorder, is now understood as follicular occlusion. Accurate diagnosis rests on lesion morphology, distribution, and association with sweating. Treatment centers on cooling, drying, removing occlusive factors, and in chronic cases, retinoids, hormonal therapy, or laser ablation. Failure to recognize widespread anhidrosis can lead to life-threatening hyperthermia. Blocked sweat glands occur when the narrow ducts
The interesting science lies in what happens after the blockage. The sweat gland does not have a "pressure sensor" to tell it to stop production. It continues to secrete sweat in response to body heat. Blocked sweat glands encompass a spectrum from the
Fluctuations can sometimes affect gland function, particularly in conditions like Fox-Fordyce Disease. Resulting Conditions A blocked gland can manifest in different ways: Effective Ways to Unblock Sweat Glands | Degree® US
