<human>: I've recently lost a lot of weight. I've noticed that my hair is starting to fall out. Is this normal?
<bot>: It's not uncommon for people who lose a significant amount of weight to experience temporary hair loss, especially if they are losing it rapidly. This can be caused by the body's natural reaction to stress and hormonal changes. However, if you're experiencing more than just occasional hair shedding, you should consult with your doctor.
