We are going to talk about fluid retention from an aesthetic point of view but above all to understand in which cases it can be due to a medical condition and requires a health professional.

Fluid retention, also known as edema, is a common problem that affects many people around the world. It is characterized by excessive fluid accumulation in the body's tissues, resulting in swelling and discomfort. Although it can be a symptom of an underlying disease, fluid retention can also be caused by several factors.

In this article, we will explore the causes and different types of fluid retention, as well as the areas of the body where it can occur. We will also talk about when it is necessary to seek medical attention. Read on to learn more about this topic!

What is fluid retention?

Fluid retention is a condition in which the body accumulates more fluid than it should. The tissues fill with excess fluid, leading to swelling and discomfort. This buildup can occur in various places on the body, such as the feet, legs, abdomen, and face. Water retention can be caused by a variety of factors, and its severity can range from mild to severe. Understanding the causes and symptoms of fluid retention is crucial to properly treating this condition.

Fluid retention, also known as edema, can be caused by different reasons. One of the most common causes is congestive heart failure, a condition in which the heart cannot pump enough blood to meet the body's needs. This can cause a buildup of fluid in the tissues. Another common cause is kidney disease, where the kidneys cannot properly remove excess fluid and waste from the body. Additionally, certain medications, such as corticosteroids, can cause fluid retention as a side effect.

Symptoms of fluid retention can vary depending on the severity of the condition. Some common symptoms include swelling in the extremities, a feeling of heaviness, joint stiffness, sudden weight gain, and difficulty moving. In more severe cases, fluid retention can cause shortness of breath, chest pain, and extreme fatigue. If you experience any of these symptoms, it is important to seek medical attention for proper diagnosis and appropriate treatment.

To treat fluid retention, it is important to address the underlying cause of the condition. If fluid retention is caused by heart or kidney disease, treatment will focus on controlling and treating that disease. Additionally, lifestyle changes such as reducing sodium intake, exercising regularly, and elevating your legs may be recommended to help reduce swelling. In more severe cases, diuretic medications may be prescribed to help remove excess fluid from the body.

Causes of fluid retention in people

There are various causes that can trigger fluid retention in people. One of the main reasons is an imbalance in the body's fluid filtration system. The lymphatic system, kidneys and blood vessels play a critical role in normal fluid balance in the body. When any of these systems do not function properly, there can be excessive fluid buildup in the tissues.

Other possible causes of fluid retention include:

  • Hormonal changes
  • Heart failure
  • Hepatic cirrhosis
  • Renal disease
  • Medication Side Effects
  • Prolonged immobility
  • Excess sodium consumption

It is important to keep in mind that each person may experience fluid retention due to different factors. If you think you are retaining fluids, it is advisable to see a doctor for a proper diagnosis.

In addition to the aforementioned causes, there are other factors that can also contribute to fluid retention in the body. One of them is the weather. In times of intense heat, it is common for people to retain more fluids due to the dilation of blood vessels and increased sweating. This can lead to a feeling of bloating and discomfort.

Likewise, excessive alcohol consumption can be another factor that contributes to fluid retention. Alcohol acts as a diuretic, meaning it increases urine production and therefore the removal of fluid from the body. However, excessive alcohol consumption can unbalance the fluid filtration system, resulting in a buildup of fluid in the tissues.

Lack of physical activity can also be a cause of fluid retention. When you don't get enough exercise, your muscles don't contract and don't help drive fluid flow through your body. This can lead to a buildup of fluid in the lower extremities, such as the feet and ankles.

On the other hand, certain medications can have fluid retention as a side effect. Some medications to treat high blood pressure, steroids, and antidepressants can interfere with the fluid balance in the body, resulting in fluid retention.

Differences between fluid retention between women and men

While both men and women can experience water retention, there are some notable differences in how this condition affects each gender. Women are generally more likely to retain water due to hormonal changes in their menstrual cycle. During certain stages of the cycle, levels of hormones such as estrogen and progesterone fluctuate, which can cause fluid retention.

In addition to hormonal changes, women also tend to have a greater amount of adipose tissue compared to men. This can contribute to increased fluid retention in some areas of the body, such as the thighs and hips.

On the other hand, men may also experience fluid retention due to underlying medical conditions or factors such as prolonged immobility or excessive sodium consumption. It is important to note that each individual is unique and may experience fluid retention differently.


In the case of women, fluid retention can be especially noticeable during pregnancy. During this period, hormonal changes are even more pronounced and can lead to greater fluid accumulation in the body. This can manifest itself in swelling of the extremities, especially the ankles and feet.

In addition to hormonal factors, lifestyle can also influence fluid retention in women. For example, excessive consumption of processed and high-sodium foods can contribute to fluid buildup in the body. Likewise, lack of physical activity and a sedentary lifestyle can hinder circulation and promote fluid retention.

For men, fluid retention may be related to medical conditions such as heart or kidney failure. These conditions can affect the body's ability to eliminate excess fluid, leading to its buildup. Additionally, some medications used to treat certain diseases can also cause fluid retention as a side effect.

It is important to note that fluid retention can vary in intensity and duration in each individual, regardless of gender. Some people may experience occasional, mild episodes of fluid retention, while others may face more chronic and severe problems. In any case, it is advisable to consult a doctor to evaluate the underlying causes and seek appropriate treatment.


In what parts of the body can a person have fluid retention?

Fluid retention can occur in different areas of the body. Here is a description of the most common areas where a person may experience fluid retention:

Fluid retention in the feet and ankles

Swelling in the feet and ankles is one of the most common symptoms of fluid retention. It can be caused by factors such as lack of movement, poor circulation, excessive sodium intake, and pregnancy. If you experience persistent swelling in your feet and ankles, it is important to seek medical attention to determine the underlying cause.

In addition, it is important to mention that fluid retention in the feet and ankles may be more common in people who spend long periods of time standing or sitting, since lack of movement can hinder venous return and favor the accumulation of fluids in this area of ​​the body. It is also important to note that wearing inappropriate footwear, such as shoes that are too tight or high heels, can contribute to fluid retention in the feet and ankles.

Fluid retention in the legs

Like the feet and ankles, the legs are also prone to fluid retention. Swelling in the legs can be caused by a variety of factors, including poor circulation, lack of physical activity, and underlying conditions such as heart or kidney failure. If you notice persistent swelling in your legs, it is advisable to see a doctor for a proper diagnosis.

Importantly, fluid retention in the legs may be more common in people who lead a sedentary lifestyle or who spend long periods of time on their feet. Additionally, certain factors such as obesity, pregnancy, and medication use can increase the risk of fluid retention in the legs.

Fluid retention in the abdomen

Fluid buildup in the abdomen can be a symptom of more serious medical conditions, such as liver cirrhosis or heart failure. If you experience persistent swelling in your abdomen, especially if it is accompanied by pain or difficulty breathing, it is important to seek medical attention immediately.

It is necessary to mention that fluid retention in the abdomen can be caused by other factors, such as excessive intake of foods rich in sodium, excessive alcohol consumption, and lack of physical activity. Additionally, certain diseases of the digestive system, such as inflammatory bowel disease, can also contribute to fluid retention in the abdomen.


Fluid retention in the face

Fluid retention on the face can be caused by several factors, including excessive sodium consumption, lack of adequate hydration, and allergies. If you notice swelling on your face, especially around your eyes, it is advisable to see a doctor to rule out any underlying conditions.

Additionally, it is important to mention that fluid retention on the face may be more common in people who consume a high-sodium, low-water diet. It has also been noted that certain medications, such as corticosteroids, can contribute to fluid retention in the face.

Fluid retention in the hands

The hands can also be affected by fluid retention. Swelling in the hands can be caused by factors such as salt and water retention, overuse of the hands, or lack of movement. If you experience persistent swelling in your hands, it is advisable to seek medical attention to rule out any underlying problems.

Importantly, fluid retention in the hands may be more common in people who perform activities that require repetitive use of their hands, such as typing or playing a musical instrument. Additionally, certain medical conditions, such as rheumatoid arthritis, can also contribute to fluid retention in the hands.


When should I go to the doctor?

If you experience symptoms of fluid retention, such as persistent swelling in different parts of the body, it is advisable to seek medical attention. A doctor will be able to evaluate your symptoms, perform a physical examination, and perform additional tests if necessary to determine the underlying cause of fluid retention.

Additionally, you should seek medical attention immediately if you experience serious symptoms, such as difficulty breathing, severe abdominal pain, or sudden changes in kidney function. These may be signs of a more serious medical condition that requires urgent treatment.
