I’m looking for advice as I’m confused. For a while I had been having symptoms of diabetes like thirsty all the time , sweating after eating , headache that goes away after I eat something with sugar. My blood pressure also drops when I sweat after eating. My doctor suggested checking the sugar levels on waking and before and after meals. On waking it was 7.4 on average and after meals roughly 9.8- 11.8. The doc told me it was likely prediabetes but I saw another doctor and they told me it is definitely not diabetes as the sugar levels would drop after eating. I had an HBa1c Test done which was normal but one of my consultants told me this could be a result of the vitamin D I was taking. Can anyone shed any light on if this could be diabetes or not as I am confused.
