Scientific details about how the pill actually works and its effects
The pill uses copies of 2 natural hormones called oestrogen and progesterone that prevent pregnancy by halting ovulation, thickening cervical mucus to block sperm and thinning the womb lining to prevent implantation. It’s absorbed into the bloodstream, processed by the liver, and excreted through the bowel, requiring daily use to remain effective.
How Your Body Processes the Pill:
Digestion: The pill is absorbed in the stomach.
Hormone Distribution: Hormones enter the bloodstream and affect body functions.
Liver Processing: Liver breaks down hormones for expulsion; not suitable for those with severe liver issues.
Excretion: Hormones are expelled through the bowel. Consistent daily use is necessary to maintain effective hormone levels.
Effects of the pill on Ovaries and Uterus:
Cervical Mucus: Becomes thicker, making it difficult for sperm to enter the womb.
Womb Lining: Remains thinner, preventing implantation of a fertilized egg.
Overall Impact: No egg release, thicker cervical mucus and thinner womb lining.
Common Side Effects of the Pill:
Nausea: About 4% of people report feeling sick.
Breast Tenderness: Around 10% experience tenderness.
Lower Sex Drive: Some may notice a reduced interest in sex; however, there's limited research linking this directly to the pill.
These side effects are generally manageable and not indicative of serious health issues.
Less Common Side Effects of the Pill:
Hair Changes: Oestrogen may thicken hair, while progestogen might reduce thickness.
Chloasma: Mild skin blemishes may appear on the cheeks and nose due to hormonal changes.
Weight Gain: Some people experience weight gain, though there’s no direct medical evidence linking it to the pill.
What to Do If You Experience Side Effects
Keep a Record: Note any side effects and track how they change over time.
Consult Your Clinician: Discuss ongoing issues, especially if they persist after three months.
Consider Alternatives: If side effects are unpleasant or persistent, try a different method.
Be Patient: Finding the right contraception can involve some trial and error, and your needs may change over time.
Conclusion
Navigating side effects from hormonal contraception can be challenging. By tracking your symptoms, consulting with your clinician, and exploring different methods, you can find a solution that works best for you. Remember, it’s normal for your needs to evolve, so be open to adjusting your method as needed.
