In recent years, the topic of maternal health has continued to attract attention, especially the issue of hemorrhoids during pregnancy has become a hot topic. Data shows that in the past 10 days, there have been more than 500,000 related discussions on the entire network, among which the search volume for the keyword "hemorrhoids in pregnant women" increased by 120% month-on-month. This article will combine the latest data and medical perspectives to analyze this problem in detail for pregnant mothers.
1. Statistics on the high incidence of hemorrhoids during pregnancy
| statistical dimension | data | source |
|---|---|---|
| Incidence of hemorrhoids in pregnant women | 35%-50% | 2023 Yearbook of Obstetrics and Gynecology |
| late pregnancy incidence | Up to 85% | Maternal and Child Health White Paper |
| Recurrence rate among mothers of second child | 72.6% | Maternal and Infant Health Platform Statistics |
| High season in summer | Incidence increased by 40% | Clinical data from tertiary hospitals |
2. Four core causes of disease
1.uterine compression effect: As the fetus develops, the volume of the uterus increases 30 times, directly compressing the rectal venous plexus, resulting in obstruction of blood return.
| Gestational age | changes in uterine weight | Increased venous pressure |
|---|---|---|
| 12 weeks | 60g→300g | 15-20mmHg |
| 28 weeks | About 1000g | 30-35mmHg |
| 40 weeks | 1100-1200g | 50mmHg or above |
2.changes in hormone levels: Elevated progesterone levels relax blood vessel walls and weaken venous valve function. According to statistics, progesterone levels in pregnant women can reach 10-15 times that of non-pregnant women.
3.Increased constipation problem: About 68% of pregnant women suffer from constipation. Increased abdominal pressure during defecation causes the rectal venous plexus to become congested and dilated.
| inducement | degree of influence | Improvement method |
|---|---|---|
| Iron supplement use | 45% increased risk of constipation | Take divided doses + vitamin C |
| Reduced amount of exercise | Intestinal motility slows down by 30% | Walk 6,000 steps a day |
| Not enough water | Stool hardness increased by 2 levels | 1.5-2L water daily |
4.Changes in diet: High-protein and high-calorie diets are common during pregnancy, and dietary fiber intake decreases by an average of 40%.
3. Prevention and Mitigation Plans
1.Step-by-step diet adjustment: It is recommended to consume 25-30g of dietary fiber daily and replenish water 5-6 times.
| food type | Recommended amount | Cellulose content |
|---|---|---|
| whole grains | 150-200g/day | 6-8g/100g |
| green leafy vegetables | 300g/day | 2-4g/100g |
| Berries | 100-150g/day | 4-6g/100g |
2.scientific exercise program: Kegel exercises can enhance the strength of pelvic floor muscles. 3 groups per day, 10-15 contractions per group.
3.Postural management skills: Lying on the left side can reduce the pressure of the uterus on the veins. It is recommended to keep it for 20-30 minutes each time.
4. Treatment precautions
1.Drug selection principles: Topical preparations containing lidocaine can be used for short-term use, but products containing steroid ingredients should be avoided.
2.Grasp the timing of surgery: Unless there is severe bleeding or incarceration, it is generally recommended to reassess the necessity of surgery 6 months after delivery.
3.TCM conditioning plan: Fumigation therapy is about 75% effective, but the water temperature needs to be controlled at 38-40°C to avoid irritation.
Conclusion:Although hemorrhoids are a common problem during pregnancy, they can be effectively controlled through scientific management. It is recommended that pregnant mothers start prevention from the early stages of pregnancy and seek medical treatment promptly when symptoms occur to avoid affecting their quality of life. The latest clinical research shows that systematic preventive measures can reduce the incidence of hemorrhoids by more than 60%.
