Introduction:

Secondary amenorrhea is a medical condition when a girl who once had a period, stopped getting it for three months or more. This should not be confused with primary amenorrhea, where a girl has a period at the age of 15 or older.

Your menstrual cycle means so much more than your reproductive functions, it is a sign of overall body health and hormone health. If your period has stopped, that indicates a part of your body has shut down and stopped working, which should not be taken lightly. 

Low Estrogen Affects the Body

Estrogen controls not only hormones but also other bodily functions, such as bone, heart, skin elasticity, and mental health. Therefore, when estrogen levels decrease, overall body health does as well, creating a chain reaction of negative effects.

Bone Health Breakdown

Osteopenia and Osteoporosis

Without estrogen, you’re prone to developing osteopenia, which indicates mild bone loss, and osteoporosis, fragile and brittle bones.

This will cause an increased chance of bone fractures and damage. Brittle bones are most likely a lifelong condition; they aren’t easily healed like cuts or bruises, which is why you must prevent it in the first place. 

Reproductive Health Risks

Ovulation and Infertility: When Periods Pause, Pregnancy Often Can’t Happen

Amenorrhea, no periods, means that you’re not ovulating. This indicates that your eggs can not be fertilized and are therefore infertile. Even if you don’t want children now, this can heavily influence your ability to conceive in the future as well. 

Atrophy and Discomfort: Vaginal Dryness, UTIs, Painful Sex

The issues around your vaginal and urinary system might be weakened/damaged. Due to lower estrogen levels, the tissues become thin, dry, and fragile.  This causes vaginal dryness and recurrent urinary tract infections.

Libido and Emotional Disconnect

Lower estrogen will lower your libido and make you feel more emotionally isolated. This will cause emotional and mental issues later on.

Mental Side Effects

Mood Swings, Anxiety, and Depression

Lower estrogen will affect the neurotransmitters like serotonin and dopamine, which influences your mood. Some side effects from this would be increased anxiety, irritability, and even depression. 

Hair, Skin, and Menopause-Like Symptoms

• Thinning hair or hair loss (temples or crown)
  
• Acne (jawline or chin)
  

• Hot flashes or night sweats
  
• Vaginal dryness, irritation, or discomfort
  
• Painful intercourse due to thinning vaginal tissue

Final Thoughts: Your Body Deserves Better

The good news is that all of these issues can be prevented if you shift your mindset and change your habits. Don’t have a calorie limit and reduce your exercise. Your health is worth much more than a number on a scale (weight is not even a clear indicator of your health). Stay strong and plan for long-term health!
