Thanks for sharing this. I can give you an internal opinion based on the numbers in the text , but I can’t safely tell you to change the dose after talking to your physician , because with
thyroid medicine the right dose depends on a few details.
From the text
* Female, 38 years
* Taking 75 mcg levothyroxine/thyroxine for ~2 years
*
TSH = 6.19 (lab range 0.35–4.94) → mildly high
* Free T3 = 2.29 → normal
* Free T4 = 0.99 → normal
* Baby is 2+ years old, breastfeeding stopped
* 75 mcg was the post-pregnancy dose
This pattern usually fits subclinical hypothyroidism / slightly under-replaced hypothyroidism:
* TSH high = pituitary is asking for more thyroid hormone
* Free T4/T3 normal = body levels are still in range
A common medical interpretation:
* TSH 6.19 is mildly elevated, and because you’re already on treatment, the doctor usually thinks about why TSH is still above target:
* dose may be a little low or
* medicine absorption issue (very common)
Before increasing dose, doctors usually check:
1. How you take the tablet
* empty stomach?
* with tea/coffee?
*
calcium/iron within 4 hours?
* missed doses recently?
2. Weight change since pregnancy
3. Symptoms: tiredness, constipation, hair fall, feeling cold, weight gain, heavy periods
4. Anti-TPO antibodies / prior diagnosis (like autoimmune thyroiditis)
5. Was the blood test done after a recent illness?
In practice, many physicians would consider a small adjustment (for example 75 → 88 mcg) if:
* TSH remains high on repeat testing after proper tablet timing, or
* symptoms are present.
But because:
* your free T4 is normal
* TSH is only mildly high
* and the dose was pregnancy-related and may need reassessment,
a very reasonable next step is:
✅ continue current tablets exactly as prescribed
✅ take correctly on empty stomach
✅  repeat TSH + free T4 in ~6–8 weeks (or sooner if your physician advised)
✅  discuss with your physician whether a small dose increase is appropriate
One question that would change my opinion:
Are you taking 75 mcg first thing in the morning on an empty stomach, and do you take calcium/iron or tea/coffee near it?
