Breasts are very soft may be related to obesity, lactation, insufficient fat content, menopause and other conditions, which need to be improved according to the cause through dietary life adjustments, exercise adjustments, surgical treatment and other methods. 1. Obesity: If the patient is overweight and too obese, then the breasts will increase in size and become soft accordingly. Women can increase exercise, such as practicing push-ups, hand-held dumbbell exercise or exercises such as bench press to make breasts fuller. 2. Breastfeeding: During the breastfeeding period, when milk is secreted, the whole breast will become full, if there is no more milk inside the breast, the whole breast will become flabby. This is a normal physiological phenomenon and does not require treatment, but care should be taken to avoid milk stagnation. 3. Insufficient fat content: If the subcutaneous fat tissue inside the breast is low, it will cause the breast to become soft. You need to eat more food rich in high protein, such as meat, eggs and milk. 4. Menopause: If a woman is in menopause, stimulated by hormone levels and ageing, the collagen in the body decreases and the skin slackens, leading to soft and sagging breasts. If necessary, it can be treated by breast augmentation surgery or breast lift. It is recommended that patients with very soft breasts seek medical attention in a timely manner and actively cooperate with the doctor for treatment.
