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?

Classical picture where patient needs upregulation of thyroxine dosage.
Need certain details to provide treatment.
1. What's your current weight.
2. When was the last dose you changed.
3. Do you have any associated symptoms of hypothyroidism?
4. With what dose you started and how it hiked up to current dosage.
5. Is your hypothyroidism post partum or you has even before your pregnancy?
Next Steps

Health Tips
It's always better to talk to a doctor before you adjust your thyroid medication dosage. Coz it's a continuous treatment and thyroxine dosage depends on your symptoms and lab reports

Your free T3 and T4 are within normal range, but your TSH of 6.19 is above the normal limit, which means your thyroid is slightly underactive despite the current dose. Since you are no longer breastfeeding and were on a post-pregnancy dose of 75mcg, it is very likely that your dose needs adjustment now â post-pregnancy thyroid requirements often differ from the long-term requirement.
Next Steps
Please consult me directly on Practo for a detailed evaluation â I can review your full thyroid profile and advise on the appropriate dose adjustment.

Hi,
TSH is mildly elevated.
The current 75 mcg dose is a bit low now. Since you’ve stopped breastfeeding, a small increase is often needed.
Do not change the dose yourself.Please consult for proper adjustment.
Feel free to consult for further guidance.👍

Your TSH is mildly elevated while Free T3 and Free T4 are within the normal range.
It is important to review your previous thyroid reports, symptoms, and how regularly you are taking the medication before deciding on any dose adjustment.
Next Steps
Feel free to consult to discuss further treatment plan.
Health Tips
Do not change the thyroxine dose on your own.

your Free T3 (2.29\text{ pg/mL}) and Free T4 (0.99\text{ ng/dL}) levels are completely normal, but your Thyroid Stimulating Hormone (TSH) is elevated at 6.19\text{ mIU/L} against the reference upper limit of 4.94\text{ mIU/L}. This specific biochemical presentation—elevated TSH with normal circulating peripheral hormones—points to mild subclinical hypothyroidism, indicating that your current 75\text{ mcg} daily dose is no longer fully meeting your body's metabolic demands.
Next Steps
You noted that your 75\text{ mcg} regimen was initially locked in as a post-pregnancy dosage, your baby is now over 2 years old, and you have fully stopped breastfeeding. Over the past 2 years, your maternal physiology, body weight, and hormone-binding globe capacities have dynamically shifted away from pregnancy baselines; these metabolic alterations explain why a dosage that kept you stable previously is now leaving you slightly under-replaced.
Health Tips
To structurally evaluate your current body weight, map any ongoing hypothyroid symptoms, and calculate the exact microgram dosage increase needed to normalize your TSH of 6.19, please book a full consultation session via my Practo profile."

If compliance is good and there are no absorption issues:
Increase levothyroxine from 75 mcg to 88 mcg daily
Repeat TSH after 6–8 weeks
Also, what is your weight and your clinical history is also important, you have developed this during the pregnancy, after the pregnancy or before the pregnancy, thats changes your medicine protocol a lot.
So I recommend you to go for a MD Medicine consultation.
