HA recovery, low fT3/fT4, normal TSH, and a short luteal phase – has anyone experienced this?
Hi everyone,
I’m currently recovering from hypothalamic amenorrhea and wanted to ask about something that has been worrying me.
I lost my period for a while, and after increasing my food intake and reducing exercise, my cycles started coming back. I’ve now had several periods again, and in my most recent cycle I had a clear LH surge and an ultrasound showing free fluid consistent with ovulation. I’m really happy that my body seems to be starting to function again.
However, I’ve noticed two things that I’m wondering could be connected to HA recovery:
1. Low fT3 and fT4 with normal TSH
My thyroid results have changed over time:
First blood test: fT3/fT4 were still at the lower end of the normal range
Second test: fT4 7.9, fT3 1.8
Most recent test: fT4 6.8, fT3 1.7
TSH: 1.92 → 1.48 → 1.65 (always normal)
I’m not taking any medication.
My gynecologist told me to have my thyroid checked again. I’m wondering whether low fT3/fT4 with a normal TSH can happen during HA, stress or recovery from low energy availability.
2. Very short luteal phase
In my most recent cycle, I had an LH peak around August 9th and an ultrasound shortly afterwards showed signs that ovulation had occurred. However, I started what appears to be my normal period only around August 14/15, which would make the luteal phase extremely short if the ovulation timing is correct.
Could this also be related to HA recovery or low thyroid hormones?
Has anyone experienced low fT3/fT4 with normal TSH and/or a short luteal phase during HA recovery? Did things improve as your recovery progressed?
I’d really appreciate hearing about your experiences.
