On the annual World Water Day, nonprofit Water.org is raising awareness for those who lack clean water access and pointing to the fact that one child dies from a water-related disease every 21 seconds.
Finally, scar tissue forms to mimic the structure of the skin before the wound to heal the tissue. That said, there are many reasons why a wound is slow to heal. Certain wounds take longer to heal than others (i.e., leg or foot ulcers). Poor nutrition can also damage the body's ability to heal wounds. Too few calories, especially from proteins, and inadequate vitamin (and zinc) intake may affect wound healing. An infected wound harboring a large number of bacteria usually slows the healing process.
Thatâs because 70 per cent of leg ulcers are venous, which means theyâve been caused when persistently high blood pressure in leg veins causes fluid to leak out, causing swelling and damage to the skin. Eventually, the skin breaks down and forms an ulcer, or open wound, typically just above the ankle. But there are other causes of leg ulcers, including poor circulation in the arteries, diabetes, inflammatory conditions such as rheumatoid arthritis, injury and leg tumours. And because the mechanisms that lead to ulcers are different, they need different treatments. Ulcers can also have a mixture of causes. The problem is a misdiagnosis can lead to the wrong treatment, with bad results. For example, if a leg ulcer is caused by a blocked artery, the cure is clearing the blockage and restoring a healthy blood supply to the foot and lower leg.
