Weakness after eating

I am 25 year old American male, living in Tokyo. Occasionally I feel very weak after eating. This began last December with absolutely no problems like it before that. The weakness is a severe physical weakness and mental blur as if all the energy has been sucked out of my body. It usually occurs 1-2 hours after eating, but it has happened immediately after eating and up to 5 hours after eating. Sometimes the weakness is so severe I feel like I'm going to pass out, and is usually followed by nausea. I have had to leave work early because of this a few times. It has happened in the morning, afternoon, and evening, but most common is late afternoon/early evening. Following these attacks I have loss of appetite for up to a few days, and on one occasion I had insomnia for 4 nights following a severe attack one evening. The doctors I see tell me it's because of an irregular lifestyle and I should eat at the same time everyday, but I have had an irregular lifestyle all my life, I don't see why this would suddenly occur. They tell me it's caused by stress, but I don't really have any stress, other than these health problems. I was reading other messages about metal toxicity, I have only 2 fillings, one big, one very small. I have made many changes to my diet, and currently I am not able to eat much at a time. I have had simple blood tests done for diabetes and parasitic infection, which were negative.

Reactive hypoglycemia is a condition which develops when the insulin response to a meal is brittle. Usually right after the meal there is an under-response and then after a couple hours, as blood glucose builds up, there is an over-response. So, if you look at the glucose level, first it shoots up, and then it takes a nose-dive. When it takes a nose-dive so does your mental energy since glucose is the energy source for the central nervous system. Although this is not yet Type II diabetes, it presages the possible development of that disorder. I suggest you be tested for reactive hypoglycemia. The proper test is a called a "glucose tolerance test." First your blood is drawn for glucose level, then you are given a very sweet drink to chug down. After that your blood glucose is measured at 30 minutes, 1, 2, 3, 4, and sometimes even 5 hours after the sweet drink is consumed. It is also helpful to measure insulin each time blood glucose is measured.

These attacks of fatigue do not occur everytime I eat, although lately they have become more frequent. I usually have no problems in the morning, even when I eat bacon and eggs, which seems to show that my actual digestive system works fine. My stool has always been normal, and I've never vomited from the nausea. The thing that is so strange to me is that I never had any stomach or health problems prior to this, and it all came on very suddenly, and seems to have gotten worse over the last few months. For the last few years I always felt sleepy after eating a big meal, just like anyone else would, but it seemed a bit stronger. I am very tall and very slim (186cm, 60kg). So is reactive hypoglycemia something that can come on so suddenly? And can it cause such severe attacks? I will have a test done soon. If it is in fact reactive hypoglycemia, what is the treatment? Is reactive hypoglycemia a chronic condition, or can one recover from it?

It is possible to recover from it, but as they say in Chineses medicine, you never not have a disease, it only goes into remission - that is to say, there will always be that weakness in the system, although perhaps not manifested.

The other possibility is that you have leaky gut syndrome. This can manifest as extreme weakness after eating and is intermittent. Usually muscle fasciculations (twitching) occurs in LGS.
