What causes dizziness, fainting and weakness?
Also the other weird thing is i experienced the exact same thing maybe 12 years ago, it slowly seemed to disappear completely, maybe 5 years later i had one episode of feeling weak/faint/palpitations and then now recently 12 years after the first episode i have been getting these episodes every day or two for the last 2 weeks.
Usually i feel either a tightness in the chest or a mild nausea and generally just feeling unwell, usually during this period i have the urge to drink a lot of water, i dont know if its thirst or just that cold water makes me feel better when im like this, then sometimes it eases off and other times i feel like im going to faint, on one occasion a couple of months ago on a plane i did fully faint but not since but felt very close to fainting a bunch of times.
Afterwards and around the time i have trouble focusing, keeping a conversation, feel foggy/dizzy/lightheaded which can last a few hours or sometimes just a short while.
I see what you are saying here.
The refractometer does not represent standard practice so I do not recommend it's use.
Some preliminary tests are necessary while we consider diabetes insipidus as a potential cause. We are essentially addressing your high water intake here.
It would be a good idea if you could quantify the amount of water you drink and the amount of urine you pass in a given 24 hour period. You will likely need to go to a nearby laboratory and collect a calibrated urine jar to ensure accuracy of collection.
Next blood tests are relevant. When I see someone like you I typically start with the following:
7 Free T4
8 Urine osmolality in a urine sample taken around the same time as the blood sample was drawn
9 Plasma free metanephrines
Further based upon the results of these, one can distinguish between the various potential causes of your complaints such primary polydypsia versus diabetes insipidus (central versus nephrogenic). These can be complex to dissect out and hence seeing an endocrinologist in person with the results will allow a systematic assessment of your problem.
Yesterday my urine density went from 1020 to 1002 over a 4-5 hour period, my understanding from reading is that 1005 to 1030 are normal ranges. 1000 basically means its completely water with no electrolytes etc
After taking diorilite which are electrolyte rehydration sachets it increased to around 1007 after around 40 mins. a couple of hours later it hit 1009 and this morning was back at 1007, then within 1.5 hours of that reading it dropped again to 1002, this is 2 days running.
What i would like to understand better is if this is normal. Yesterday i had maybe 3-5 pints of water, 3 of those sachets for rehydration and a 500ml bottle of sprite. This morning i had a pint of water, then 200ml of water with the sachets, i woke at 10am when it was 1007 and had the pint of water then and within 90 mins it was 1002 when i took the XXXXXXX before it went lower.
What could cause this to drop like this, all i done in that time was to walk down to the doctors maybe 5 mins away and back and i was sitting in the waiting room in between. Is there another possible cause that my sodium levels are dropping like this. Several other people in the house have taken the test and they are all ranging from 1012-1035 over several tests throughout the day.
To be honest inspipidus sounds unlikely because from reading people urinate very frequently, i only get that after getting an episode of feeling weak/dizzy then i will urinate 4-6 times per hour for maybe an hour or two and usually drink anything up to 2l of water within an hour of feeling well as the cold water seems to help so i drink as much as i can. Normally within 30-40 mins i start to feel better but now these sachets seem to be preventing it getting that far which is good.
I understand what you are saying.
However, please note that there is no published evidence based scientific medical guideline to go by the urine specific gravity, in analyzing your complaints.
I am not sure if this was deployed in previous decades but certainly in modern medicine the approach to your problems is largely with the help of universally standardized criteria that primarily include
Based upon the results of these, it may be necessary to perform a Water restriction test
I am sorry I cannot guide on refractometer readings as they do not represent standard of care.
