Sodium levels

Hi. Wonder if anyone has had this

My blood sodium levels was 130 range 135-145

Retested , then 133 .

No further investigation. GP said it was normal .

I looked this up and hypothyroidism is the only thing that applies to me.

I noticeable pee less in the day . I did end up in hospital going back when sodium level was 128 and I was vomiting and quite unwell .

Do you think an increase in thyroxine might help ?

Helpful link on low sodium

Not all that helpful, as they advise restricting water as treatment. When I had a lobectomy, they tested blood every day. My sodium came back low and they walked out of the room with my water pitcher and refused to allow me to order more than 2 cups of liquid per day. I quickly became dehydrated. I couldn't generate enough saliva to swallow solid food so I stopped eating. Then they gave me a bottle of Ensure. If this ever happens to me again, I will refuse the treatment of water restriction and ask instead that they give me sodium in some form -- salt tablets (like those taken on a hike), or Gatorade, which replaces electrolytes.

What happens to you if you add salt to water and drink it throughout the day?

You haven't mentioned whether or not you are restricting salt or drinking more liquids than you need, or both.

Someone on the forum wrote a thread about excluding salt from her diet and how it backfired on her badly - you may find it of interest :

Thanks both , I have tea and coffee 5/6times s day and have to remind myself to drink plain water .

So not over hydration in my case .

I have now added more salt to cooking and some on food .

I will see if that makes the difference.

I happen to be having a zoom call from a Endo on Wednesday this week .

So will talk about these latest results to him.

Both urine and blood osmolality was abnormal. Bring very low .

Have symptoms but not sure what caused them !

Endo might help ?!!!

I see from this wiki link :

en.wikipedia.org/wiki/Hypon...

that low sodium can have a lot of causes.

Given that you are hypothyroid, and just on the basis that adrenal problems are quite common with hypothyroidism, I would want to be tested for Addison's Disease in your shoes.

But the number of possible causes is huge so you would need an endo to take your situation seriously, unlike your GP saying that low sodium is "normal". 🙄

A link you might find helpful for future reference if you do get tested thoroughly is to the Endocrine Bible. It details the preparation necessary for certain tests, what to expect, how to carry out testing, what the results might mean, for any of the tests that a normal endocrine department in a UK hospital might do.

Good luck.

I been wondering if their is a connection with sodium levels and hypothyroidism …. 3 months ago my TSH shot up and my sodium level had dropped and felt sluggish but earlier this month my TSH was pretty low and my sodium was high… I do sodium for other issues wasn’t done for thyroid problems… interesting.

I guess understanding the intricacies of the body workings are a long way off . If looking at a range regarding this say 1 to 100. We /docs are at about 3 ,

Many layers of the onion to go yet , me thinks

Oh, but on here a better score than that which is handed out by the medics . .

Some are better than others ! Sadly in the minority in my experience .

What thyroid medication are you now taking

What vitamin supplements and what are your most recent vitamin D, folate, ferritin and B12 results

Previous post shows you were under medicated

TSH. 0.23. 0.27- 4.2

T4. 16. 12-22

T3. 2.8. 3.1-6.8

Hi, subsequent to take test because of GP pressure to lower Levo I dropped T3 . So that so taking just T4. 75mcg. (Which they wanted to lower to 50mcg) ! When I got the result I then added back my T3 at 10 mcg as I had been doing.

Test taken last Thurs week unexpectedly so I had taken both T4 snd T3 at about 5am that morning and the bloods were done at 4pm that same day.

Those are reported as ft 4 15.7pmol/l

Ft 3. 5.1 pmol/L

So not bad for me .

TSH wasn’t taken as the doc (hospital) said the TSH will be suppressed if taking T3 !!!!

I take 2000 vit d and k2

However my gp is to test (when I can get an appointment for blood draw) folate snd b12

So I won’t take anything until that is done .

GP is happy with those low numbers , I just wonder if I would feel better if they were in range .

Hemaglobin, red blood , and hematacrit all below range also .

Not much hope in the health service at gp level sadly .

To make progress you likely need to test yourself regularly

Vitamin D twice year when supplementing

Folate, ferritin and B12 at least annually

That might not be high enough dose vitamin D

Do you normally supplement vitamin B complex?

TSH, Ft4 and Ft3 6-8 weeks after any dose change or brand change in levothyroxine or T3

ALWAYS test as early as possible in morning before eating or drinking anything other than water and last dose levothyroxine 24 hours before test

Day before test

Divide T3 dose into 3 smaller doses, roughly equal 8 hour intervals with last 1/3rd of daily dose 8-12 hours before test

Thanks SD. I will get to it . Quality of life is the aim .

At the end of the day that’s what we all want

I’ve developed low sodium levels on several occasions when hospitalised - also potassium.

I get prescribed bags of crisps and bananas. Soon sorts it out.

The levels you describe are not anything to worry about.

Ok thanks. I might just add a bit more salt . Maybe enough to fix it. Thanks

in reply to Gcart

Not too much 😉

Gcart,

Yes, I think optimising thyroid hormone will help because low sodium is commonly due to compromised adrenals. Is your BP ok?

Ask your GP to test cortisol and aldosterone. During investigation for a constant thirst mine were found to be low, together with low sodium. Aldosterone is a mineralocorticoid that regulates the balance of sodium & water in the kidneys.

It is important to replace the missing salt so I used to eat lots of salted crisps and even put salt in glasses of water. Surprisingly nothing really tasted salty until sodium levels eventually increased as cortisol issues rectified after several years of optimal thyroid hormone.

You can tell if you are consuming too much salt because will feel nauseous and/or swollen. Also BP might raise above normal readings. You may find supporting the adrenals with a glandular or adaptogen helps recovery faster. This should also invite thyroid hormones to work more effectively.

Your GP should retest electrolytes in a few weeks to ensure sodium levels aren’t dropping further and potassium levels remain normalised, especially as you have experienced similar issues previously.

I get white coat high blood pressure . At the time I feel relaxed and am not at all worried! 180/86 is about normal then.

At home and most of the time it’s 125/70

Wish I knew why that happened.

Thanks for your input . I think I might try a small increase in T4 as it’s mostly been in the lower quarter of range ,
