We don't always know if it's fat or swelling, but there are ways of finding out the cause of the bulge and, even better, solutions to put an end to the problem.
Cai um mito: Não mais poderemos justificar o nosso excesso de peso com a retenção de líquidos. A especialista em gestão do peso, Prof. Teresa Branco, é perentória: «Se há peso a mais, é porque há gordura a mais. Com o peso vem também a retenção de líquidos mas esta raramente aparece sozinha.
Fat or bloating: how to tell the difference
Is excess weight due to fluid retention common?
Usually not. When you're overweight, it's usually because you have too much body fat. However, the heavier a person is, the more likely they are to accumulate fluids, so excess weight can be a little higher due to fluid retention.
What is fluid retention in practice?
It is an accumulation of fluid, mostly water, both intra and intercellular, i.e. inside and outside the cells, especially in fat cells, causing swelling in the body and consequent weight gain.
Is it more common in men or women?
It's much more common in women because, in general, we have more body fat and more female hormones, which are responsible for this situation.
How do hormones influence fluid retention?
When there isn't enough progesterone (the female hormone that influences the second part of the menstrual cycle) being produced, fluid retention can occur, which, if controlled, is actually beneficial, as the body needs water to function well and if it's out of control it's important to have more water, but not too much.
«Mulheres que tomam a pílula têm maior propensão para a retenção de líquidos porque têm uma diminuição acentuada da produção de hormonas sexuais, nomeadamente a progesterona que é uma hormona drenante»
And at what age is it most common?
Geralmente é na pré-menopausa, ou seja, na fase que antecede a menopausa. Nesta fase, que se pode prolongar por muitos anos, é frequente haver desequilíbrios entre os níveis de progesterona e estrogénios (com predominância do estrogénio) levando à retenção de líquidos.
Is there a genetic propensity?
Sim, algumas pessoas têm maior predisposição. No entanto, isso pode ser contornado pelo estilo de vida, fazendo uma alimentação com menos sal, menos bebidas gasosas e ricas em açúcar e menos alimentos processados. A retenção de líquidos também é acentuada pelo stresse, pela inatividade física e pela toma de anticoncecionais hormonais.
Are women who take the pill more likely?
Yes, because they have a marked decrease in the production of sex hormones, particularly progesterone, which is a draining hormone. The hormones in the pill don't compensate for the body's decreased production, not least because they're not exactly the same as ours. The latest generation of pills are a little better, but not ideal.
"When there is fluid retention, people have a large daily weight variation"
How much weight can you gain from fluid retention alone?
It varies greatly from person to person. Thinner women retain less weight and can retain one to two kilos. People who are heavier can retain two to three kilos.
How can you tell the difference between excess weight due to accumulated fat and fluid retention?
When there is fluid retention, people experience a large variation in their daily weight, which can fluctuate greatly from day to night. In addition, their eyes, hands, feet and ankles may also feel swollen.
Are there any other symptoms?
Yes, they may also feel less energetic and their clothes feel tighter at certain times of the day.
Are there any medications or illnesses that contribute to fluid retention?
Yes, particularly health problems that cause hormonal variations such as thyroid disorders and progesterone deficiency. Some medications, especially cortisone-rich drugs, can contribute to increased fluid retention.
Are there any differences between a diet plan to counteract fluid retention and a diet focused on reducing fat mass?
There isn't much difference because in both situations we need to eat a healthy diet that will help us reduce weight and, at the same time, eliminate excess fluids.
