It may be hypoglycemia. (low blood sugar)Sometimes when a person with low blood sugar gets hungery or burns a lot of calories quickly, their blood sugar can take a big dive. This causes tremors, weaknes and the person can even pass out. It's not dangerous unless it becomes very frequent. If your husband is over forty, he should see his doctor about it anyway just to be sure.
The treatment for an infrequent problem is pretty simple. He needs to eat balanced meals on time every day. If he like to eat sweet stuff, he should eat it on a balanced meal so he won't peak and then crash. Reasonable exersize helps. If your husband is into athletics or is away from home a lot, he needs to carry some kind of energy food. Granola bars have both simple and complex carbohydrates so they give a quick boost and long lasting energy. They keep good in the car trunk too.
At home, keep a couple 12oz cans of apple or orange juice in the fridge. If your husband gets the shakes, a can of juice should help him recover. I advise against candy because it can lead to a second, even bigger crash.
