Whether sagging breasts can be recovered depends on the degree of sagging and the factors that caused it. The difficulty of recovery varies because different factors cause sagging breasts. For mild breast sagging, there is no obvious atrophy of the gland, in this case, as long as appropriate chest massage and chest exercises such as chest expansion are performed, most patients can regain their breast shape. However, for moderate to severe breast sagging, or congenital macromastia with breast sagging, there is usually atrophy of the glands and usually cannot be fully restored, but the breast shape can be enhanced through surgical procedures, depending on the individual situation. If the breast sagging occurs in old age, it is basically irreversible and is a normal condition, so keep a good attitude. Adhering to exercise can effectively delay aging and sagging breasts. To avoid sagging breasts, you should avoid unreasonable dieting and weight loss, strengthen chest exercise, change bad sleeping posture and wear proper underwear.
