Prolonged skipping of carbohydrates may cause endocrine disorders and finally cause no menstruation. Carbohydrates are the main source of energy needed to maintain life activities. When you do not eat carbohydrates for a long time, it will lead to poor digestion and absorption function, poor nutritional status, metabolic dysfunction and other conditions, causing endocrine disorders. For female patients, endocrine disorders are likely to lead to menstrual disorders and other problems. You should pay attention to reasonable diet and establish a healthy diet structure to avoid the occurrence of some diseases caused by partiality. If there is no menstruation, you should go to the hospital in time, and take reasonable methods of treatment under the guidance of the doctor.
