Health care is not really available when you live hours from a hospital, so people must take care of their own medical problems.
It seems that urine and mares milk can cure anything. We were staying at a ger where the 18 month old girl had a fever in the middle of the night. When the mother woke, she gave her some urine when she had nothing in her stomach (apparently this is important). A couple of hours later, the girl was better. Mare's milk, which is a staple of their diet, is used to treat a variety of diseases including broken bones (I have my doubts about that one).
On the plus side, if you can get to the hospital, the care is completely free.
