thank you for your helpful information my daughter is nine and had her third seizure last night she has'nt had one in several years of course i was terrified she seems to be fine this morning but very tired thank you again for info
I understand your concern. Let me try to organize my response so it makes sense and addresses your concerns.
1. You ask about recovery. Yes, it takes a few days to recover. He needs to test more often and absolutely avoid ANY lows for a period of supposedly about 2 weeks after a severe low like this, or he may start to lose his warning symptoms of lows. Studies have shown that when this happens, called 'hypoglycemic unawareness' (a very dangerous situation for we diabetic people when the body no longer lets us know when we are dropping too low), the warning symptoms CAN BE RECOVERED. Supposedly a period of about 2 weeks without any lows at all can help the body clear away any residues of emergency sugars released by the liver (a normal response to a severe low) so that the brain can properly recognize a low if it starts to happen. So test more often than usual for a few weeks to help the body recover this very important ability. If he did not wake up when his glucose levels dropped a little bit, then he may indeed have some hypoglycemic unawareness, and this would help him recover the brain's ability to wake him if his glucose levels are dropping.
2. As for sore muscles, I have been there, done that. It sounds like his doctor is helping with muscle relaxants. Hot showers or baths help ease the discomfort, too.
3. The torn-up tongue (OUCH!) will just have to heal. Fortunately, mouths heal quickly.
Now, as for long-term damage, it is commonly thought that there really is no long-term damage. However, some recent studies do indicate that people who have had lots of severe lows MAY display some memory loss. This doesn't affect overall intelligence or ability to problem-solve, but some memory issues may surface. No real solutions for this, if it happens. The best thing to do is to take this very seriously and figure out how to avoid having this happen.
You don't say what kind of insulin regimen your son is on. So I am only going to throw out a suggestion that works for many people who take Lantus insulin at bedtime and quick-acting insulins such as Novolog or Humalog before meals. Lantus is marketed as a 24-hour insulin, but it DOES have a very slight peak action 4-5 hours after injection. For some people (myself included), this peak action is more noticeable than for other people, and can actually be the cause of some night lows. For those of us with this problem, the solution is to talk to his doctor and slowly over a period of time, start to change the evening dose to become a morning dose, with maybe a few units injected at bedtime just to keep sugars from rising too high while the morning dose peters out in our sleep. For me, this has completely removed the danger of severe night lows. Occasionally, if I misjudge something, I can get a LITTLE low while I sleep, but never to the point of seizure since I changed my timing of Lantus from night to morning. He would need to work with his doctor to slowly do this over a period of a week or so if this is something that would help.
Maybe he needs to have something handy at all times to cover him if he is just too beat to eat when he comes home. A meal-in-a-shake might help. Or maybe he needs to set his alarm to wake him about half-way through the night to check his sugar levels on those nights. Feeling extreme fatigue at bedtime for me is usually a warning sign that sugar levels may actually be on their way down even if normal when I test before bedtime. I sleep with two 6-oz. cans of apple juice right by my bed in case I wake up in the night, and on those nights when fatigue is noticeable, I do test in the middle of the night. Better to be safe and wake up once than to risk seizure.
