Why Do I Gain Weight Around My Period? Understanding Hormonal Swings
Weight gain around your period is mainly caused by hormonal fluctuations in estrogen and progesterone, which lead to water retention, bloating, increased appetite, and temporary changes in digestion. This is not true fat gain. For some Malaysians with significant hormonal or metabolic challenges, medically guided options such as Ozempic or Mounjaro may support appetite and insulin regulation under supervision.
Key Takeaways
Period-related weight gain is usually water retention, not fat gain
Estrogen and progesterone shifts drive bloating and appetite changes
Cravings and fatigue are hormone-driven, not due to willpower
Weight typically normalises after menstruation begins
Medical guidance can help if symptoms are severe or persistent
Understanding Period-Related Weight Fluctuations
Many Malaysian women notice the scale rise in the week before their period. This can feel discouraging, especially when diet and exercise have been consistent. The good news is that this is a normal hormonal response, not real weight gain.
The menstrual cycle affects:
Fluid balance
Appetite regulation
Digestion speed
Energy levels
Blood sugar control
Together, these create a temporary increase in scale weight that usually resolves within a few days.
How Estrogen and Progesterone Affect Your Weight
Estrogen
As estrogen rises before ovulation and falls before menstruation, it can:
Increase water retention
Affect serotonin (mood and cravings)
Change how your body handles carbohydrates
Progesterone
Progesterone rises in the second half of the cycle and can:
Slow digestion
Increase appetite
Promote bloating
Raise body temperature and fatigue
These hormonal changes explain why you may feel heavier, hungrier, and more bloated before your period—even without eating more.
Why You Crave More Food Before Your Period
Hormonal shifts affect both insulin sensitivity and brain appetite signals.
Common premenstrual changes include:
Stronger cravings for sugar and carbohydrates
Reduced blood sugar stability
Lower energy and motivation for workouts
Increased emotional eating
These responses are biologically driven, not behavioural failure.
Is It Real Fat Gain?
In most cases, no. Period-related weight increases are mainly due to:
Water retention
Glycogen storage (carbs stored with water)
Slower digestion
Temporary bloating
True fat gain requires a sustained calorie surplus over time, not a few premenstrual days.
Lifestyle Factors That Can Worsen Period Weight Gain
Certain habits can amplify hormone-related weight changes:
High-sodium Malaysian foods (soups, sambal, sauces)
Poor sleep
High stress
Low protein intake
Skipping workouts due to fatigue
Managing these factors can significantly reduce bloating and scale fluctuations.
Practical Ways to Manage Period-Related Weight Changes
1. Prioritise Hydration
Drinking more water actually reduces fluid retention.
2. Increase Protein Intake
Protein stabilises blood sugar and controls cravings.
3. Maintain Gentle Movement
Light cardio and strength training improve circulation and reduce bloating.
4. Support Sleep and Stress
Poor sleep raises cortisol, which worsens water retention and cravings.
5. Be Consistent, Not Reactive
Avoid crash dieting or extreme restriction during this phase.
For some women with PCOS, insulin resistance, or significant appetite dysregulation, medically guided treatments such as Ozempic or Mounjaro may help regulate hunger and blood sugar when prescribed by a doctor.
When to Seek Professional Guidance
Medical evaluation is recommended if you notice:
Persistent or significant weight gain
Irregular menstrual cycles
Extreme fatigue or heavy bleeding
Possible hormonal conditions, such as PCOS or thyroid issues
Strong cravings despite consistent diet and exercise habits
A licensed provider can assess hormonal balance, insulin sensitivity, thyroid function, and overall metabolic health. For Malaysians seeking professional guidance, OVA Malaysia offers medically guided consultations to discuss weight-loss options and next steps.
The Takeaway
Weight gain around your period is common, temporary, and driven by hormonal changes. It is usually due to fluid retention, increased appetite, and digestion shifts rather than actual fat gain. Managing it effectively involves consistent nutrition, sufficient sleep, stress management, and realistic physical activity.
For Malaysians seeking extra support with appetite control and metabolic health, OVA Malaysia offers medically guided programs that may include treatments such as Ozempic or Mounjaro under professional supervision, helping to support safe and sustainable weight-loss goals.
