Hi there 😊
If you have an under active thyroid can it affect your cholesterol level as I've always been fine but since being diagnosed my cholesterol level is slowly been increasing & I have now been told that I need to change my diet.
I have also had to cut out gluten, is this all connected?
Thank you
If your thyroid hormone levels are too low, your cholesterol levels will rise.
Diet is massively over-blamed for cholesterol levels - very little cholesterol gets into your body as cholesterol in food. Most is made in your body and it appears carbohydrates, especially sugars, are significant.
I suspect that you are under-dosed.
I'll leave others to disucss gluten.
This suggests you aren’t on high enough dose of levothyroxine
How much levothyroxine are you currently taking?

If you have an underactive thyroid (hypothyroidism), treatment may be delayed until this problem is treated. This is because having an underactive thyroid can lead to an increased cholesterol level, and treating hypothyroidism may cause your cholesterol level to decrease, without the need for statins. Statins are also more likely to cause muscle damage in people with an underactive thyroid.
For full Thyroid evaluation you need TSH, FT4 and FT3 plus both TPO and TG thyroid antibodies tested. Also EXTREMELY important to test vitamin D, folate, ferritin and B12
Low vitamin levels are extremely common, especially if you have autoimmune thyroid disease (Hashimoto's) diagnosed by raised Thyroid antibodies
Ask GP to test vitamin levels and redo FULL thyroid
You may need to get full Thyroid testing privately as NHS refuses to test TG antibodies if TPO antibodies are negative
Recommended on here that all thyroid blood tests should ideally be done as early as possible in morning and before eating or drinking anything other than water .
Last dose of Levothyroxine 24 hours prior to blood test. (taking delayed dose immediately after blood draw).
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip, best not mentioned to GP or phlebotomist)
Is this how you do your tests?
Private tests are available. Thousands on here forced to do this as NHS often refuses to test FT3 or antibodies
thyroiduk.org.uk/tuk/testin...
For thyroid including antibodies and vitamins
Medichecks Thyroid plus ultra vitamin or Blue Horizon Thyroid plus eleven are the most popular choice. DIY finger prick test or option to pay extra for private blood draw. Both companies often have special offers, Medichecks usually have offers on Thursdays, Blue Horizon its more random
If you can get GP to test vitamins and antibodies then cheapest option for just TSH, FT4 and FT3 £29 (via NHS private service )

The aim of Levothyroxine is to increase the dose slowly in 25mcg steps upwards until TSH is under 2 (many need TSH significantly under one) and most important is that FT4 is in top third of range and FT3 at least half way through range
NHS guidelines on Levothyroxine including that most patients eventually need somewhere between 100mcg and 200mcg Levothyroxine.
nhs.uk/medicines/levothyrox...
Also what foods to avoid (eg recommended to avoid calcium rich foods at least four hours from taking Levo)
All four vitamins need to be regularly tested and frequently need supplementing to maintain optimal levels
Add results and ranges if you have them.
Or Come back with new post once you get new test
Thank you everyone 😊 Xx
How much levothyroxine are you currently taking?
When was dose last increased
I'm on 50mg 5 times a week & 75mg twice a week! The GP has said my thyroid levels are good
That’s a really tiny dose

NICE guidelines
cks.nice.org.uk/hypothyroid...
The initial recommended dose is:
For most people: 50–100 micrograms once daily, preferably taken at least 30 minutes before breakfast, caffeine-containing liquids (such as coffee or tea), or other drugs.
This should be adjusted in increments of 25–50 micrograms every 3–4 weeks according to response. The usual maintenance dose is 100–200 micrograms once daily.
All four vitamins need to be regularly tested and frequently need supplementing to maintain optimal levels
Even if we start on low 50mcg dose, it still needs to be increased upwards in 25mcg steps
New NICE guidelines
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.
BMJ clear on dose required

Why worry about cholesterol levels? Studies show that those with ‘high’ cholesterol live longer. Your body makes 90% of all cholesterol so what you eat has very little to no impact. I’m not an expert but do read Dr Kendrick.
