Why have diarrhea before menstruation? Analysis of the causes and coping methods of diarrhea during menstruation
Many women experience various discomfort symptoms before their period, with diarrhea (digestion) being a common but less discussed issue. This phenomenon is not accidental, but is closely related to hormone changes in women's physiological cycle. This article will analyze the causes of premenstrual diarrhea in depth and provide scientific basis and practical suggestions.
1. Common causes of premenstrual diarrhea
| reason | Specific mechanism | Incidence ratio* |
|---|---|---|
| Elevated prostaglandin levels | Stimulates uterine contraction and affects intestinal peristalsis | About 68% |
| Changes in hormone levels | Estrogen and progesterone fluctuations affect intestinal function | About 52% |
| Pressure reaction | Increased premenstrual stress leads to "brain-intestinal axis" disorder | About 45% |
| Changes in eating habits | Premenstrual appetite changes may consume more irritating foods | About 30% |
*Note: The data are derived from statistics from multiple gynecological studies, and there may be overlapping situations
2. The key role of prostaglandin
Before menstruation, the endometrium secretes prostaglandin, the main function of this substance is to promote the uterus to contract to help excrete the endometrium. However, prostaglandin is not "specific" and it will also affect the intestinal smooth muscle, causing rapid intestinal peristalsis, which will cause diarrhea symptoms.
3. Specific impact of hormone fluctuations
| Hormone type | Change trends | Effects on the intestine |
|---|---|---|
| Estrogen | Sharply before menstruation | May slow down intestinal peristalsis |
| Progesterone | Significantly reduced before menstruation | Relieve the relaxation effect on the intestinal tract |
The "retreatment effect" of this hormone makes the intestine suddenly become sensitive and prone to overreacting to a normal diet.
4. Practical suggestions for dealing with premenstrual diarrhea
1.Dietary adjustment: Reduce dairy, caffeine and high-fat foods in the previous week, and increase digestible carbohydrates such as rice, bananas, etc.
2.Nutrient supplements: Magnesium and calcium help relieve menstrual discomfort and can be supplemented in moderation; probiotics can help maintain the balance of intestinal flora.
3.Moderate exercise: Gentle aerobic exercises such as walking and yoga can regulate hormone levels and relieve the impact of stress on the intestines.
4.Heat compress relieves: Abdomen hot compress can relax the uterus and intestinal muscles and relieve spastic pain and diarrhea.
5.Drug intervention: Nonsteroidal anti-inflammatory drugs (such as ibuprofen) can inhibit prostaglandin synthesis, but must be used as directed by doctors.
5. When do you need medical treatment?
Although premenstrual diarrhea is usually normal, seek medical treatment in time if the following conditions occur:
- Diarrhea is accompanied by severe dehydration symptoms (dizziness, extreme thirst, significant reduction in urine volume)
- Diarrhea lasts for more than 3 days and does not relieve
- Bloody or black stool
- Significant weight loss
- Seriously affecting daily life and work
6. Identification from other diseases
| Symptoms and characteristics | Menstrual period-related diarrhea | Irritable bowel syndrome | Inflammatory bowel disease |
|---|---|---|---|
| Time of occurrence | 1 week before menstruation to the end of menstruation | It may happen at any time | Continuity |
| Accompanied symptoms | Menstrual discomfort such as breast swelling | Belly bloating, exhaust | Fever, anemia, etc. |
| Stool characteristics | Watery stool but no abnormal ingredients | There may be mucus | Possible pus blood |
7. Prevention and long-term management
1.Record the symptom cycle: By recording menstrual cycles and digestive symptoms, you can better predict and prepare.
2.Adjust your lifestyle: Regular work and rest, adequate sleep and stress management can all help relieve symptoms.
3.Traditional Chinese Medicine Conditioning: Some women have improved through traditional Chinese medicine to regulate qi and blood, warm and nourish the spleen and kidneys, but they need to be guided by professional doctors.
4.Psychological adjustment: Recognize that this is a physiological phenomenon shared by many women, and there is no need to be overly anxious.
Although premenstrual diarrhea is uncomfortable, it is usually a natural physiological reaction of the body. By understanding the causes and taking appropriate measures, most women can effectively alleviate this symptom. If the problem persists or worsens, it is recommended to consult a gynecologist or gastroenterologist for more targeted guidance and treatment.
