Hi, I have been diagnosed hypothyroid for 4 years. I have now been diagnosed with high blood pressure. I have had call back on my kidney function since taking the BP meds for a month. Is this all linked. Thank you

You can't be diagnosed with high blood pressure. It's a symptom, not a disease. And, it is very often a symptom of hypothyroidism. Perhaps you are under-medicated. Do you have a copy of your latest blood test results?
Hi greygoose, get that BP is a symptom. I haven't got my last full readings. My TSH was 3.5
Then you are definitely under-medicated. It should come down to 1 or under. With a TSH of over 3 you are still hypo, and your high BP is more than likely related to that. You need an increase in levo, not BP medication.
Thank you. GPs don't listen unfortunately

On levothyroxine TSH should ALWAYS be below 2
Most people when adequately treated will have TSH around or under 1
How much levothyroxine are you currently taking
poor kidney function and low GFR directly linked to being hypothyroid and will improve as dose levothyroxine is increased
ncbi.nlm.nih.gov/pmc/articl....
cureus.com/articles/138958-...
Bloods should be retested 6-8 weeks after each dose change or brand change in levothyroxine
For full Thyroid evaluation you need TSH, FT4 and FT3 tested
Also both TPO and TG thyroid antibodies tested at least once
Very important to test vitamin D, folate, ferritin and B12 at least once year minimum
About 90% of primary hypothyroidism is autoimmune thyroid disease, usually diagnosed by high thyroid antibodies
Autoimmune thyroid disease with goitre is Hashimoto’s
Autoimmune thyroid disease without goitre is Ord’s thyroiditis.
Both are autoimmune and generally called Hashimoto’s.
Low vitamin levels are extremely common when hypothyroid, especially with autoimmune thyroid disease
20% of autoimmune thyroid patients never have high thyroid antibodies and ultrasound scan of thyroid can get diagnosis
In U.K. medics hardly ever refer to autoimmune thyroid disease as Hashimoto’s (or Ord’s thyroiditis)
Recommended that all thyroid blood tests early morning, ideally just before 9am and last dose levothyroxine 24 hours before test
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins

request/politely insist on 25mcg dose increase in levothyroxine
And get thyroid antibodies and vitamins tested via GP now
Or include in full thyroid test 6-8 weeks after increasing dose levothyroxine
guidelines on dose levothyroxine by weight
Unless extremely petite likely to need to be on at least 100mcg levothyroxine per day
Even if we frequently start on only 50mcg, most people need to increase levothyroxine dose slowly upwards in 25mcg steps (retesting 6-8 weeks after each increase) until eventually on, or near full replacement dose
NICE guidelines on full replacement dose
nice.org.uk/guidance/ng145/...
1.3.6
Consider starting levothyroxine at a dosage of 1.6 micrograms per kilogram of body weight per day (rounded to the nearest 25 micrograms) for adults under 65 with primary hypothyroidism and no history of cardiovascular disease.

Guiding Treatment with Thyroxine:
In the majority of patients 50-100 μg thyroxine can be used as the starting dose. Alterations in dose are achieved by using 25-50 μg increments and adequacy of the new dose can be confirmed by repeat measurement of TSH after 2-3 months.
The majority of patients will be clinically euthyroid with a ‘normal’ TSH and having thyroxine replacement in the range 75-150 μg/day (1.6ug/Kg on average).
The recommended approach is to titrate thyroxine therapy against the TSH concentration whilst assessing clinical well-being. The target is a serum TSH within the reference range.
……The primary target of thyroxine replacement therapy is to make the patient feel well and to achieve a serum TSH that is within the reference range. The corresponding FT4 will be within or slightly above its reference range.
The minimum period to achieve stable concentrations after a change in dose of thyroxine is two months and thyroid function tests should not normally be requested before this period has elapsed.
I too have high blood pressure which has been treated for a long time - I was unaware of the link with hypothyroidism until I was diagnosed and started, with the help of this forum, researching the condition. At the time of diagnosis I had poor kidney function, high cholesterol and elevated glucose. Since starting on thyroxine - am now on 100mcg - my kidney function and blood glucose have returned to within range levels and my cholesterol level is almost back to what is acceptable. My GP had been pressing me to take statins - am so pleased I refused! Am also hoping to be able to reduce my BP meds…watch this space!
