According to data from the public opinion monitoring platform, the number of discussions related to "pregnant women's foot health" has surged in the past 10 days, mainly concentrated on the following platforms:

2. Three main causes of foot rot in pregnant women
Based on dermatology data from tertiary hospitals, foot problems during pregnancy are mainly divided into three categories:
| Type | Proportion | Typical symptoms | High incidence period |
|---|---|---|---|
| fungal infection | 43% | Peeling, blisters, erosion | second and third trimester |

3. In-depth analysis of pathogenesis
1. Hormone changes trigger chain reactions
Elevated progesterone levels cause:
• Decreased skin barrier function (30% increase in transepidermal water loss)
• Strong sweat gland secretion (the amount of sweating on the feet is twice that of ordinary people)
• Immunosuppressive state (shift in Th1/Th2 balance)
2. Changes in physiological structure
Clinical measurements show:
• Foot length increases by an average of 8-10mm in the third trimester
• 62% of pregnant women suffer from foot arch collapse
• Increased venous pressure to 1.5 times that of non-pregnant women
4. Comparison of prevention and control measures
| measures | effectiveness | Things to note |
|---|---|---|
| Medical elastic stockings | 78% improvement rate for vein problems | Need to measure leg circumference to select model |
| antifungal care | Symptom relief rate 65% | Avoid oral azoles |
| blood sugar control | Ulcer recurrence rate reduced by 90% | Requires dynamic monitoring of OGTT |
