low energy. just over 40 and exhausted most of time

[schooling123]

i cant believe myself...i used to be so energetic, on the go etc and now cannot get out of my bed in the morning, when with my kids so lethargic and tired. what is this? is it health issue?

We would have no idea unfortunately!

See your GO and request a blood test

GP

Could be underactive thyroid or vitamin D deficiency. Need a comprehensive blood test to see what's going on.

i checked m6 blood and thyroid hormones. all ok

B 12? It's a separate test to full blood count.

i take B12 every day

What's your diet like? How carb-heavy is it? How much water do you drink? And do you do any exercise?

Do you know what your serum ferritin levels were - did they test that? I'd find out. If your vitD, B12 and thyroid have been ruled out I would find out about ferritin. At the lower end of the accepted range you can get many of the symptoms of anaemia, including awful fatigue. Could it be hormonal? I'm peri and I know my energy levels fluctuate a lot.
