My seven year-old overheats very quickly and becomes unusually lethargic in the sun. He is given plenty of water, but obviously has trouble cooling himself. Unlike some of his friends, his sweat glands don't seem to have kicked in yet. At the end of a hot day, his shirt will smell like it just came out of the dryer. This surprises my husband and I as we are both rather heavy in the perspiration department. We are concerned about our son suffering from heat stroke under normal play/school p.e. conditions. Our family doctor seemed unconcerned about this problem at this point, but we get worried as we watch him wilt in the sun. Thank you for the assistance
It is difficult to pinpoint a cause without further examination.
The most obvious thing to check would be for thyroid conditions, since it can cause symptoms related to temperature regulation. Blood tests to investigate this possibility should be considered.
If there are issues with the sweat glands, rheumatological conditions (i.e. Sjogren's) can be considered, as well as some uncommon endocrine diseases.
A referral to an endocrinologist can be considered to discuss these possibilities.
