You could certainly attribute dizziness or falls to extreme low or high blood sugar.

Need more info...: To figure out the reason for your symptoms, more information is needed. For example, are you diabetic since diabetes is a common etiology for high triglycerides? Did you have pain in the back of your neck and then dizziness or just the dizziness? If your symptoms persist, perhaps you should see a neurologist to try to figure out the cause of your dizziness. Good luck! ...Read more

Possibly: Polyuria (freq urinating) and polydipsia (thrist) are indeed very common in diabetes. You should have it checked if these are new symptoms for you. A simple blood, test such as fasting glucose, would give you the answer. ...Read more

I took 1 5mg melatonin 20hours ago now, had horrid nightmares and now I feel off and dizzy, almost drunk. My blood sugar is fine. Can it cause this?

I took 1 5mg melatonin 20hours ago now, had horrid nightmares and now I feel off and dizzy, almost drunk. My blood sugar is fine. Can it cause this?

Yes: You reminded me of own personal experience with melatonin. I tried 3 mg at bedtime and felt too groggy and "off" the next day. I don't like it but many of my patients find it helpful. Melatonin is deemed a "food additive" by the fda and does not come under the scrutiny that medication does. The doses we take are vastly greater than the quantities produced in the brain so I am a bit leery about it. ...Read more
