Introduction

In general, whether weight loss is advisable during lactation should be determined based on the mother's physical recovery, breastfeeding needs, and the specific weight-loss method being considered. If any discomfort or uncertainty occurs, it is recommended to consult a physician promptly. When considering weight loss during lactation, one should avoid extreme methods such as dieting or taking weight-loss medications to prevent harm to health and interference with breastfeeding. Close attention should be paid to one's physical condition throughout the weight-loss process.

Generally speaking, whether weight loss is possible during lactation should be determined based on the mother's physical recovery, breastfeeding needs, and the weight-loss method being used. If there is any discomfort or uncertainty, it is advisable to consult a doctor promptly. Detailed analysis is as follows:

If the mother has recovered well postpartum, her milk supply is stable, and it meets the baby's needs, she may moderately lose weight by adopting a combination of dietary adjustments and gentle exercise. This approach does not excessively drain the body, helps avoid excessive calorie intake, and generally does not affect breastfeeding or maternal health while ensuring breast milk nutrition.

If the mother's physical recovery is poor, or if her milk supply is insufficient and the baby frequently cries and relies on breastfeeding for comfort, weight loss is not advisable at this time. The body needs to focus its energy on recovery and maintaining milk production. Engaging in blind dieting or high-intensity exercise may lead to nutritional deficiencies, affect the quality and quantity of breast milk, and potentially increase physical strain, delaying recovery.

During lactation, if considering weight loss, one should avoid extreme methods such as strict dieting or taking weight-loss medications to prevent harm to health and interference with breastfeeding. During the weight-loss process, close attention should be paid to physical condition. If symptoms such as fatigue, dizziness, or reduced milk supply occur, weight loss should be immediately stopped and adjusted accordingly. The pace of weight loss should not be too rapid; a recommended rate is no more than 0.5 kilograms per week, balancing both health and breastfeeding needs.

What causes a bitter taste in the mouth?

Bitter taste in the mouth may be caused by factors such as imbalance of the oral environment, emotional and neurological regulation, gastrointestinal motility disorders, abnormal liver and gallbladder metabolism, or medication effects. It is recommended to maintain a daily water intake of more than 1500 ml, consume moderate amounts of hawthorn and dried tangerine peel to aid digestion, and avoid smoking and limit alcohol consumption. If bitter taste persists for over a week or is accompanied by abdominal pain, jaundice, or significant weight loss, you should visit a gastroenterology or dental clinic for further evaluation, including gastroscopy.
