1. Androgenetic alopecia

Medical · Dermatology Abbreviations

The most common form of hair loss, known as male- or female-pattern hair loss, caused by genetically determined sensitivity of hair follicles to androgens. Men lose hair at the temples and crown, while women typically experience diffuse thinning over the top of the scalp with a preserved frontal hairline.

Example: AGA, Norwood III vertex; start finasteride 1 mg and topical minoxidil 5 percent.

Patterns are graded with the Hamilton-Norwood scale in men and the Ludwig or Sinclair scales in women. Topical minoxidil and oral finasteride are the long-standing approved treatments, and low-dose oral minoxidil is increasingly used off-label. In obstetrics and pediatrics AGA means appropriate for gestational age.

2. Appropriate for gestational age

Medical · Obstetrics & Gynecology Abbreviations

Birth weight between the 10th and 90th percentiles for gestational age, the classification for most newborns. It is recorded in newborn assessments alongside SGA and LGA.

Example: Term male, 3,420 g, AGA, Apgars 8 and 9; routine newborn care.

Growth charts such as Fenton or WHO standards are used to determine the percentile. A baby can be AGA yet still have experienced slowed growth late in pregnancy. In dermatology AGA means androgenetic alopecia.
