    WHAT DISEASES CAUSE LOW FERRITIN?

    Low ferritin levels are a common finding on blood tests and often raise questions about iron stores and overall health. Ferritin reflects how much iron your body has stored, and when levels are low, it can point to underlying medical conditions rather than diet alone.

    WHAT DOES FERRITIN LEVEL TELL YOU?

    Ferritin levels offer valuable insight into how much iron your body has stored and how well it can meet its ongoing needs. While iron is often discussed in relation to anaemia, ferritin goes a step further by showing whether iron reserves are low, adequate, or elevated. Because symptoms linked to iron imbalance can be vague and develop gradually, ferritin testing is often used to investigate unexplained fatigue, weakness, or changes in physical performance.

    WHAT ARE 5 SIGNS YOUR BLOOD SUGAR IS TOO HIGH?

    High blood sugar, also known as hyperglycaemia, can develop gradually and may go unnoticed for some time. In the early stages, symptoms are often subtle and easily mistaken for everyday fatigue, dehydration, or stress. Because of this, many people do not realise their blood sugar is elevated until levels remain high for a prolonged period or complications begin to develop.

    WHAT DOES HCG DO TO A WOMAN?

    HCG is best known as the hormone that confirms pregnancy, but its role in a woman’s body goes far beyond a positive test result. From the earliest stages of pregnancy, hCG helps drive hormonal changes that support implantation, maintain the uterine lining, and influence many of the symptoms experienced in the first trimester. Changes in hCG levels can also provide valuable information about how a pregnancy is progressing.

    WHAT BETA HCG LEVEL INDICATES MISCARRIAGE

    In early pregnancy, beta hCG levels are often used to help assess how a pregnancy is developing. When results fall outside expected patterns, it can raise understandable concern about miscarriage and what the numbers actually mean. Many people search for a specific beta hCG level that confirms miscarriage, but hormone levels are rarely that straightforward and must be interpreted carefully.

    WHAT DO OESTRADIOL LEVELS TELL YOU?

    Oestradiol is the main and most active form of oestrogen in the body. Measuring oestradiol levels can provide valuable insight into hormone balance, reproductive health, and how the body is functioning at different life stages. Because oestradiol affects many systems, including the reproductive organs, bones, brain, and cardiovascular system, changes in its levels can help explain a wide range of symptoms.

    HOW SMALL DO TESTICLES GET ON TRT?

    Testosterone replacement therapy is commonly prescribed to treat symptoms of low testosterone such as fatigue, reduced libido, low mood and loss of muscle mass. While many men experience clear improvements in how they feel, a frequent concern before starting treatment is whether TRT causes the testicles to shrink and, if so, how noticeable those changes might be.

    IS TRT LEGAL IN THE UK?

    Many men who are concerned about low testosterone or considering hormone treatment wonder whether testosterone replacement therapy is legally available in the UK. With so much conflicting information online, it can be hard to know what is permitted and how the legal framework affects access to treatment. Understanding how TRT is regulated and prescribed helps clarify what is legal, who can prescribe it, and what steps are required to access therapy safely and appropriately.

    WHAT DOES TRT DO FOR A MAN?

    Testosterone replacement therapy, often shortened to TRT, is a medical treatment used when a man’s testosterone levels are consistently lower than they should be. Testosterone plays a central role in male health, influencing physical strength, sexual function, mood, energy levels and bone health. When levels drop below the normal range, some men experience symptoms that affect daily life.
