Medicine Net explains: “Birth control pills and hormone replacement therapy for menopause have oestrogen, an essential female hormone that can make blood clot more easily.

“The chance is small; only one in 1,000 women taking birth control pills each year get deep vein thrombosis, but the chances may be higher if you use a patch, which has 60 percent more oestrogen than a pill, or if you’re at risk for other reasons, too.

“Men who use testosterone, a male hormone, are also more likely to get clots.”

Air travel, too, is known to impact the body’s blood clotting system, which can lead to small increases in the risk of deep vein thrombosis.
