Our blood sugar is influenced by various factors throughout our lives, including age, lifestyle, and, importantly, hormones. Hormones play a key role in regulating blood sugar, and fluctuations in hormone levels can cause changes in how our body manages glucose. These shifts look different in men and women due to the unique hormonal cycles each experiences. 

The Role of Hormones in Blood Sugar Regulation

Hormones such as insulin, cortisol, oestrogen, progesterone, and testosterone all influence how our body regulates blood sugar:

• Insulin is a hormone produced by the pancreas that allows cells to use glucose from the bloodstream. It is the key player in maintaining normal blood sugar levels.
• Cortisol, the stress hormone, raises blood sugar by signalling the liver to release stored glucose, ensuring the body has enough energy during stressful situations.
• Oestrogen and progesterone, the primary female sex hormones, fluctuate throughout the menstrual cycle, pregnancy, and menopause, impacting insulin sensitivity and blood sugar levels.
• Testosterone, the primary male sex hormone, plays a role in regulating muscle mass and fat distribution, which can impact insulin sensitivity.

Blood Sugar and Hormones: A Lifelong Relationship

Adolescence and Early Adulthood

Puberty brings dramatic hormonal shifts that can start influencing blood sugar regulation. Oestrogen and progesterone in girls and testosterone in boys both affect how the body responds to insulin, which can cause fluctuating blood sugar levels.

• Girls and Adolescence: During the menstrual cycle, blood sugar may fluctuate due to changes in oestrogen and progesterone levels. These hormones impact insulin sensitivity, often leading to cravings, fatigue, and mood swings.
  PCOS (Polycystic Ovary Syndrome): PCOS, a hormonal disorder affecting many women, often begins in adolescence. It leads to insulin resistance, causing higher blood sugar levels, weight gain, and increased risks of type 2 diabetes. Women with PCOS may experience more significant blood sugar fluctuations due to elevated levels of androgens and insulin resistance, making it important to monitor glycemic control closely.
• Boys and Adolescence: Testosterone, which increases muscle mass, improves insulin sensitivity during adolescence. However, periods of rapid growth and hormonal changes can cause temporary insulin resistance, leading to variable blood sugar levels.

Adulthood: The Balancing Act

For most adults, glycemic control becomes more challenging as stress levels increase and lifestyle factors like diet and exercise begin to impact blood sugar more significantly.

• Women and Hormones: Throughout the reproductive years, women’s oestrogen and progesterone levels fluctuate during the menstrual cycle. In the luteal phase (the second half of the cycle), progesterone rises, and insulin sensitivity often decreases, leading to higher blood sugar levels. Pregnancy also introduces dramatic shifts, with the possibility of gestational diabetes due to hormonal changes that impact insulin sensitivity.
  PCOS remains a challenge in adulthood for many women, as the condition can worsen with age, contributing to obesity, insulin resistance, and metabolic complications.
• Men and Hormones: Testosterone levels are relatively stable in early adulthood but begin to decline with age. Testosterone promotes lean muscle mass, which helps regulate insulin sensitivity and glycemic control. As testosterone levels decrease, men may experience higher blood sugar levels and a greater risk of developing type 2 diabetes.

Midlife and Beyond: Menopause and Andropause

As we approach midlife, hormonal changes become more pronounced, especially in women with menopause and in men with andropause (the gradual decline of testosterone).

• Women and Menopause: During menopause, oestrogen levels drop significantly, leading to a decrease in insulin sensitivity. Oestrogen has a protective effect on glucose metabolism, so its reduction often results in increased blood sugar levels. This is why many postmenopausal women are at higher risk for developing insulin resistance and type 2 diabetes. Weight gain, especially around the abdomen, is also more common, which further exacerbates blood sugar control. 
• Men and Andropause: Men experience a gradual decline in testosterone as they age, known as andropause. Lower testosterone levels lead to reduced muscle mass and increased fat accumulation, which in turn decreases insulin sensitivity and raises the risk of metabolic syndrome and type 2 diabetes. Men may also experience mood swings and fatigue as a result of this hormonal shift, similar to women going through menopause.

Managing Blood Sugar Across Life Stages

While hormonal fluctuations are inevitable, there are ways to support glycemic control throughout life. Here are some strategies for managing blood sugar through different life stages:

1. Balanced Nutrition:
   Consuming a balanced diet with low glycemic index (GI) foods helps prevent blood sugar spikes. Focus on fibre-rich vegetables, lean proteins, and healthy fats to maintain stable energy levels.
2. Regular Exercise:
   Physical activity increases insulin sensitivity by helping muscles use glucose more efficiently. Regular exercise is particularly helpful as hormone levels fluctuate in both men and women.
3. Stress Management:
   Since cortisol can raise blood sugar levels, managing stress through relaxation techniques like yoga, meditation, or deep-breathing exercises can help keep blood sugar balanced.
4. Monitoring Blood Sugar:
   For those with significant blood sugar fluctuations, continuous glucose monitoring (CGM) can provide real-time insights into how hormones, meals, and activities affect glucose levels, making it easier to adjust lifestyle choices.
5. Hormone Optimisation:
   For some people, hormone replacement therapy (HRT) or testosterone therapy may be helpful in managing blood sugar levels as they age. Our clinic can assess whether hormone therapy is right for you.
