A sudden 5–6 kg weight gain within one month at age 38 should not automatically be assumed to be body-fat gain. It is important to first identify whether the increase is due to fluid retention, hormonal changes, increased calorie intake/reduced activity, or an underlying medical condition.
☆ As a nutritionist, I would suggest evaluating :-
1.
Thyroid function:
TSH and Free T4, particularly if there is fatigue, constipation, feeling cold, dry skin/hair fall or menstrual changes. Hypothyroidism can contribute to weight gain.
2. Menstrual/perimenopausal changes: At 38, hormonal fluctuations can affect appetite, fluid balance and body weight.
3, Water retention: Check for swelling/puffiness of the face, hands, feet or ankles. High sodium intake, hormonal changes and some medications can contribute to fluid retention.
4. Diet and lifestyle changes: Increased portions, eating out, sugary drinks, alcohol, reduced physical activity, poor sleep or increased stress can all contribute to weight gain.
5. Medications: Recent use of steroids, some antidepressants, hormonal medicines/contraceptives or other medications can sometimes contribute to weight gain or fluid retention.
Health Tips
Because 5–6 kg in one month is relatively rapid, I would recommend getting a medical evaluation rather than simply starting a restrictive weight-loss diet. Depending on symptoms/history, a doctor may consider
TSH, Free T4, fasting glucose/
HbA1c, CBC,
kidney/
liver function and other tests as clinically indicated.
