Baseline labs should include LH, FSH, estradiol, progesterone, thyroid hormones, prolactin, fasting insulin, and metabolic markers
Without enough B12, these cells can become large and misshapen (megaloblastic anaemia), reducing oxygen flow to your brain and muscles, causing fatigue and weakness
That kind of deep, never-ending fatigue
The diagnostic process typically involves: Clinical history taking, focusing on symptoms (fatigue, neurological changes, dietary habits) Physical examination for signs of anaemia or neurological impairment Blood tests including full blood count, serum B12, and often folate levels Additional investigations such as intrinsic factor antibodies or parietal cell antibodies if pernicious anaemia is suspected For borderline results, additional tests like holotranscobalamin (active B12) may be considered NICE guidance recommends that treatment should commence based on clinical presentation if neurological symptoms are present, without waiting for laboratory confirmation, as delays can result in irreversible nerve damage
Copper peptides are naturally occurring tripeptides that bind to copper ions, creating a biologically active complex that plays a key role in tissue repair and regeneration
The sequence is proline-rich, with three consecutive prolines followed by a fourth at position eight, and that conformationally constrained backbone is the usual structural explanation offered for the resistance
