My husband has experienced the following: severe nausea, sweating and then weakness. He is 75 years old. After eating something it went away. He did eat breakfast and this was in the early afternoon.

If: If after eating something these symptoms went away, the diagnosis could be hypoglycemia (low blood sugar). Some elderly individuals can develop what is called post prandial hypoglycemia, that is their blood sugar start to fall after few hours of having a meal to the point that they start to have symptoms.

A couple hours after eating breakfast, I started feeling slightly weak again, as though I hadn't eaten in a couple days. What is wrong with me?

Low blood sugar?: Not sure if this is the answer, so I have a speculating, but based on your story, perhaps your blood sugar is dropping too low after eating breakfast. A good test would be to see if eating something with sugar makes you better quickly. If it does, you might consider actually seeing a doctor and getting some labs drawn to sort this out. Good luck. ...Read more

Make sure you have protein and some fat in your breakfast too. Those calories take longer to be digested and enter the blood after the carbohydrates, helps you got 4-5 hours between meals. ...Read more
