Estrogens: essential hormones for female and male health
Estrogens are a key group of sex hormones that regulate the female reproductive system and the menstrual cycle, but their influence also extends to the health of bones, the heart, the brain, and the skin. The main types of estrogens in humans are estradiol, estrone, and estriol. They are produced primarily by the ovaries, though small amounts are synthesized in the adrenal glands and other tissues.
These hormones are responsible for developing secondary sexual characteristics, such as breasts and body hair, and they support skin elasticity. An important aspect of health is the balance between estrogen and progesterone, and fluctuations in estrogen levels are associated with menopause and various physiological conditions.
Understanding the role of estrogens helps both women and men maintain optimal health, taking into account the natural changes in hormonal balance throughout life.

Progesterone: Key Hormone for Reproductive Health and Balance
Progesterone is a steroid hormone that plays a central role in the female reproductive system and overall health. It is mainly produced by the ovaries after ovulation and by the placenta during pregnancy. Its primary function is to prepare the endometrium for implantation of a fertilized egg and to create optimal conditions for embryo development. Low progesterone levels can lead to fertility issues or increase the risk of miscarriage.
Beyond its role in the uterus and pregnancy, progesterone regulates the menstrual cycle, supports breast tissue preparation for breastfeeding, and influences mood and a sense of calm. It interacts with brain receptors and other hormones like estrogen to maintain hormonal balance in the body.
Monitoring progesterone levels is important for women with irregular cycles, difficulties conceiving, or during pregnancy to ensure optimal health and safety.

Hypertension: A Clear and Simple Explanation
Hypertension, commonly known as high blood pressure, is a condition in which the force of the blood pushing against the artery walls remains higher than normal over time. This isn’t just a temporary spike — it’s a long-term strain on the heart and blood vessels.
When blood pressure stays elevated, the heart has to work harder to pump blood throughout the body. Over time, this extra effort can weaken the heart, damage blood vessels, and affect organs such as the brain, kidneys, and eyes. Because hypertension often has no obvious symptoms, many people are unaware they have it until complications appear.
If left untreated, hypertension can lead to serious health problems, including heart attack, stroke, kidney disease, and vision issues. The good news is that it can be managed through lifestyle changes and, when necessary, medication prescribed by a healthcare professional.

Cortisol: clear and understandable explanation
Cortisol is a hormone produced by the adrenal glands, often called the “stress hormone”. Its levels increase when the body reacts to tension, fatigue, or physical activity. However, cortisol also has many important functions.
It helps the body handle challenging situations by providing extra energy, improving focus, regulating inflammation, and maintaining blood sugar balance. In normal amounts, cortisol is completely natural and essential for proper body function.
Problems arise when cortisol levels remain high for a long period. This can lead to fatigue, anxiety, sleep disturbances, weight gain, and weakened immunity. Maintaining a healthy lifestyle and managing stress effectively are therefore essential for keeping cortisol in balance.
