I've found since my thyroid removal op, my mucus levels vary in tune with my thyroxine intake. When I'm low, I'm a bit 'dry' nasally, when I'm on the up stroke ( and my Endo has decided I'm actually very low for the gazillionth time and upped my meds), I get a slightly blocked nose as my mucus membranes come back into operation. My nose (sorry ladies) has a slight crust inside it for a few days, whilst my thyroxine increases. I have no cold symptoms, I have no flu symptoms, only a booger filled nose for several days.
I've noticed this several times since having my thyroid taken out, but never seen much discussion on it. I have also , intestinal problems ,which mainly manifests itself in lactose intolerance. I'm kind of working on a theory that these two events are tied in.
Your villi, the little 'tongues' which pass the food through your gut, rely on mucus production to deal with the food. This could be the seat of my 'post op' lactose intolerance.
Can anyone relate to this? It might be a bit odd, but its the only way I can tie all the symptoms into one real causation....mucus production.
