It is not uncommon for girls to have sagging breasts at a certain angular rate as they get older , but the tendency of sagging breasts in adolescence does not fall into the stage of normal physical changes. Possible causes of sagging breasts include adolescent weight gain , childbearing , smoking, or having large breasts due to heredity, and not wearing the necessary bra / proper size bra on large breasts. Symptoms: Women resort to breast ligaments ; If these ligaments are stretched , the natural position of the breast usually comes down due to loss of muscle strength. Breast implants can be easily inferred from the displacement of the nipple (coming down to the very bottom of the breast) and the skin folds on both sides of the breast. Causes: The most common cause of sagging breasts is excessive and heavy breasts , or inadequate breast support. Due to childbirth i.e. during pregnancy the size of the breast becomes larger and due to holding the breast it becomes heavier and as a result the breast may become loose. It should be noted here that breastfeeding does not change the shape of the breast. At the same time, during high impact exercises such as running , dancing, etc., if you do not use a sports bra or a full-bodied bra, it is possible to sag the breasts! Things to consider: Many women worry - does breastfeeding have anything to do with sagging breasts ? But studies have shown that there is no negative relationship between breastfeeding and changes in breast size and shape. According to the Myoclinic website, the reason for sagging breasts during pregnancy is a sudden change in the size of the breasts and later on it decreases again in a short period of time. Solution: In adolescence, steps should be taken to prevent sagging breasts so that the ligaments of the breast do not expand and the elasticity of the breast skin is not lost. Since direct or indirect smoking weakens the elasticity of the skin, non-smokers are less prone to breast sagging than non-smokers. Maintaining a healthy body weight and adequate breast augmentation in high-impact exercise and daily living can prevent breast sagging. A report published in the July 2010 issue of the Journal of Medicine in Sports and Exercise states that sports bras that are able to fully lift and hold overweight breasts during work prevent women's discomfort as well as breast size / shape change. Caution: Any abnormal changes in the size / shape of the breast and changes in the position , size or shape of the nipple may be a precursor to other difficult problems. You should do monthly breast self-monitoring. Record any sudden changes. If you have any abnormalities in the size of your breasts, do not hesitate to consult a doctor as the shape of your breasts may change due to the presence of tumors.
