Hi, and welcome to our forum.
I have been diagnosed with RH. After a few hospital tests.
I found an endocrinologist who recognised the symptoms, because of me going hypo in GP surgery then in front of my endocrinologist twice.
RH is food intolerance. And the treatment is avoidance of those foods that trigger the reaction.
There is not a way I can definitely suspect you have hypoglycaemia, but because of your other conditions, you can't rule out anything, you need a referral to an endocrinologist, ifyou don't already have one. To get the necessary tests done.
There is no cure.
But you can control your blood glucose levels and help yourself to a better health.
You mention you eat a healthy diet, it you do have a condition similar to RH, a so called healthy diet might be the problem. It is the carbs, sugars that need to be avoided, healthy carbs are still carbs and cause spikes, which I know would trigger a reaction.
Again, if you have a similar condition, a glucometer and keeping a food diary is important to show your doctor what is happening.
You also mentioned low energy, I suspect that because of your other conditions, your dietary regime is contributing to this. You need carbs for energy, but it is not enough, sugar crashes because of the spikes, are symptomatic with various levels of hormones such as insulin, other contributing factors are lifestyle.
The difference a very low carb diet did for me was remarkable.
I am eating fresh food every day. I am eating a keto diet. Which means I get my energy from ketones rather than carbs.
I am on a drug called sitagliptin. This helps with my first phase insulin response. Which in turn prevents the spikes, if I mistakenly do have carbs. Which in turn reduces the reaction of overproducing insulin.
We do have our own forum, have a read, there is a lot of information and knowledge on those looking for advice.
As you will see, there are many forms of hypoglycaemia and similar symptoms that cover a wide range of non diabetic and diabetic conditions.
Best wishes
