Link between hypothyroidism and raised levels of creatinine?

I have Hashimoto's and believe I am undermedicated.

Recent blood tests showed TSH at 5.5 and also a raised creatinine level which I am worried about. Have to repeat blood test this week.

Sodium, potassium and urea levels were fine.

Any thoughts?

Only that I have the same. I have Hashi's and my latest bloods show raised creatinine. I am on holiday away from Saudi where I work so have not had an opportunity yet to discuss with my Endo. I think the upper level shows 60 and mine was 77.

Sorry, I also meant to say when my last bloods were taken I was also undermedicated.

Creatinine can be high in hypothyroidism due to reduced clearance. My creatinine was high when I was very hypo and OK when I was still a bit hypo. You need more hormone, I don't know of any reason why the high creatinine should worry you.

Yes, that's what I thought.

But I am still worried as it could be early sign of CKD?

You would need to see your doctor about that. I assume you have and they should have explained the high creatinine to you. Was your levothyroxine increased after the TSH 5.5 result? Just retesting without a change in dose would be daft (and par for the course).

Official NHS guidelines saying TSH should be between 0.2 and 2.0 when on Levothyroxine

(Many of us need TSH nearer 0.2 than 2.0 to feel well)

See box

How much Levothyroxine are you currently taking?

Essential to test vitamin D, folate, ferritin and B12. Always get actual results and ranges. Post results if/when you have them, members can advise

Hashimoto's affects the gut and leads to low stomach acid and then low vitamin levels

Low vitamin levels affect Thyroid hormone working

All thyroid tests should be done as early as possible in morning and fasting and don't take Levo in the 24 hours prior to test, delay and take straight after. This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, GP will be unaware)

Hi Helena12. I'm writing here because I'm looking for a skilled, professional, serious endocrinologist in London. As I've just read your request for recommendations dated 2017, so I think it might be a good idea to ask you if you have met one. My email, should you prefer to write privately, is latavernadelliris1@yahoo.it . Thank you in advance.

Not what you're looking for?
