Armpit fat, more accurately referred to as axillary fat, in females can be caused by a combination of factors including genetics, excess body fat, bra fit, and, less commonly, accessory breast tissue.
Here's a breakdown of the contributing causes:
-
Genetics: Your genes play a significant role in determining where your body stores fat. Some women are genetically predisposed to store more fat in the underarm area.
-
Excess Body Fat: Overall weight gain can lead to increased fat storage throughout the body, including the armpit area. This is often the most common cause.
-
Bra Fit: Incorrect bra size and style can significantly contribute to the appearance of armpit fat.
- Too Tight: Bras that are too tight can squeeze the skin and fat from the breast area and push it towards the armpit, creating the bulge.
- Incorrect Style: Bras with cups that don't fully contain the breast tissue can also contribute to the issue.
-
Accessory Breast Tissue (Axillary Breast Tissue): In some women, breast tissue can extend into the armpit area. This is called accessory breast tissue or axillary breast tissue. This is less common but can appear as noticeable "fat" in the armpit, often fluctuating with hormonal changes (e.g., menstruation, pregnancy). It is actual breast tissue, not just fat.
Here's a table summarizing the causes:
| Cause | Description |
|---|---|
| Genetics | Predisposition to fat storage in the armpit area. |
| Excess Body Fat | Overall weight gain leading to increased fat storage. |
| Improper Bra Fit | Bras that are too tight or the wrong style can push breast tissue into the armpit. |
| Accessory Breast Tissue | Presence of breast tissue extending into the armpit area. |
In summary, while genetics and overall body fat contribute to armpit fat, the fit of your bra can often exacerbate the appearance. Consider getting professionally fitted for a bra to ensure proper support and minimize the appearance of underarm bulge. If you suspect accessory breast tissue, consult with a doctor.
