“I had been suffering from vague symptoms for years, such as tiredness, low energy, melancholy moods and constant fluctuations in weight. Because of my age, the menopause was assumed to be a likely cause. But at some point, I felt that this seemed too easy a conclusion. Serna took extensive energy measurements which enabled us to identify the cause (medication use). After discussing it with my specialist, I reduced my medication and now I feel much better. I have more energy, feel able to handle things and, an added bonus: my weight has stabilised.”
