The 32-year-old has been battling a slew of physical side-effects and struggling with PTSD since the traumatic birth of her son Leo nine months ago.
Updating her followers on her health, the E4 star wrote on her Instagram Stories: “Harley Street clinic is iconic. Just had my appointment with the kindest and most trustworthy obs/gyne... it’s likely that I have adhesions inside my uterus causing something called Asherman’s Syndrome.
“A hysteroscopy would offer a better look inside the cavity than an ultrasound but because I might need to start thinking immunosuppressants, having non essential surgery isn’t really an option.
"The main impacts of Asherman’s are: painful cramping and fertility problems. (sic)”
Earlier in the day, Louise revealed that she had decided to go private for a scan on her pelvis because her last ultrasound was “inconclusive”, and she would’ve had to wait “months longer” for a follow-up appointment on the NHS.
Sitting in the back of a car wearing her hood over her head, she told her 1.4million followers: “Going to go and have a scan of my pelvis. First one in about 3 months. The NHS are saying I’ll have to wait months longer for a follow up appointment, so I’m going private...
“Bit of a joke really when I still don’t have any answers as to what’s going on in that region and the last ultrasound was ‘inconclusive’ and the guy joked that it looked like there was something white and shiny in there.
"My cramping has started to get pretty bad and I still haven’t had a menstrual cycle 10 months sooooo."
Thompson also revealed that she had been given an “investigation report” of her ill-health but is “afraid” to read it.
“I actually received an investigation report with details thicker than the complete works of Shakespeare the other day but I’m afraid to open it.
“I was also scheduled to have a private hysteroscopy (small camera inside) in July but it coincided with my readmission to hospital for my ulcerative colitis, so it’s been on the back burner.
“Sometimes I can’t believe this is my life” (sic).
The reality star has been struggling with PTSD and post-natal anxiety since she almost died twice when giving birth to her son last November.
Thompson has bravely shared her struggles online in the hope that her story can help others.
