DVT in Pregnancy
Deep vein thrombosis (DVT) occurs when a blood clot forms in one or more deep veins of the body, most commonly in the legs. While DVT can occur in non-pregnant women, pregnancy increases the risk up to five times. This is due to increased pressure in the veins of the pelvis and legs during pregnancy. Women with inherited clotting disorders are particularly susceptible. The risk of DVT can persist for up to six weeks after delivery.

Symptoms and Causes
Many cases of DVT have no noticeable symptoms. When symptoms do appear, they may include:
- Swelling in the affected leg, particularly in the ankle and foot
- Pain or tenderness in the leg
- Cramping in the calf
- Changes in skin color, such as redness, paleness, or bluish discoloration
DVT can develop after prolonged periods of immobility, such as long car or plane journeys, or due to medical conditions that increase blood clotting. During pregnancy, limited movement can raise this risk. To help prevent DVT:
- Perform gentle calf exercises by raising and lowering your heels while seated
- Stretch and move your legs as much as possible throughout the day
Risks of DVT
DVT can become serious if a blood clot breaks free and travels to the lungs, potentially causing a pulmonary embolism, which can block blood flow and become life-threatening.
