Gynecomastia Is Prevailing In Men Above 44 Years Old

SINGAPORE, December 2019 — Gynecomastia is the presence of excess glandular and/or fatty breast tissues in man. It is the result of an enlargement of the glandular component of the breast. Gynecomastia is not just an aesthetic problem; it is also a medical condition, which can be detrimental to health. Common symptoms include tenderness around the breast, swelling of the breast gland tissue, and more.

Causes Of True Gynecomastia

Being overweight, contrary to misconception, is not the cause of the condition. True gynecomastia is caused by hormone imbalance. Certain medications are also the cause of the condition, especially amongst older patients. Over time, these medications can cause a hormonal disturbance and imbalance, which can lead to the development of glandular type gynecomastia.

Gynecomastia Cases Are Increasing In Men Above 44 Years Old

In a “Gynecomastia As A Physical Finding In Normal Men1” study by Nuttal on 306 normal adult men ranging in age from 17 to 58 year-olds, 57% of those subjects with palpable gynecomastia are those over the age of 44. The finding alludes that gynecomastia becomes more prevalent with age and thus, must be taken into consideration when attributing gynecomastia to a drug or disease state.

Statin, Amoxicillin, And Proton Pump Inhibitors Increase Gynecomastia Risk

Medications for high cholesterol (statin), bacterial infections (amoxicillin) and gastrointestinal diseases (proton pump inhibitors) are at higher risk of developing gynecomastia.

Case reports in 2018 on “Statin Medications And The Risk Of Gynecomastia2” by Skeldon et al. have suggested an increased risk of gynecomastia with statins, a class of drugs often prescribed to help reduce cholesterol levels in the blood. However, this meta‐analysis also found that statins decrease circulating testosterone levels in men, thus increasing the risk of gynecomastia.

Medications in the form of proton-pump inhibitors (PPIs) and amoxicillin, commonly used in the treatment of a wide variety of bacterial infections, have also been shown to cause gynecomastia in users. According to a study3 conducted from 2006 to 2016 on new PPI users and new amoxicillin users, there were 389 cases of gynecomastia diagnosed among 220,791 new PPI users, and 996 cases diagnosed among 837,740 new amoxicillin users.

Gynecomastia Can Also Be Found In All Age Groups For Men

A clinical research4 was conducted on 305 gynecomastia patients (555 breasts) who underwent surgical treatment from 1997 to 2015. The objective of the study by Fricke et al. (2018) was to analyse the histological differences in young and old patient groups.

From the findings, older patients are found to have florid (nodular) gynecomastia, while fibrous gynecomastia was more common in adolescents and young adults. Patients presenting with florid gynecomastia showed a higher rate of recurrence than patients with the fibrous type of gynecomastia.
