Rapid Weight Gain Symptoms
Rapid or unintentional weight gain happens when your weight increases without increased consumption of food or decreased activity.
Symptoms associated with rapid weight gain can be different between each person. But most people will immediately notice that clothing items such as shoes and pants no longer fit. ### Associated symptoms of rapid weight gain can also include: ###
- Abdominal discomfort
- Sensations of bloating
- Swelling in the abdomen and extremities ( arms, legs, feet or hands)
- Stretch marks on the abdomen or thighs
- Puffiness or swelling of the face
Rapid unintentional weight gain is not a normal process and should always be followed up with your physician. These symptoms usually signal an underlying medical issue.
Rapid Weight Gain Causes Overview
Causes of rapid, unintentional weight gain can be separated into three broad categories. Endocrine disorders, systemic conditions that cause fluid retention and medications.
The endocrine system is a series of glands that produce hormones important in the regulation of metabolism, growth and development. Both normal functioning and dysfunction in this system can cause rapid weight gain for multiple different reasons.
- Reproductive : The endocrine system is responsible for the regulation of the reproductive functions in the body such as pregnancy and the menstrual cycle. Rapid weight gain within certain ranges during pregnancy is normal as the body puts on extra weight in form of the baby, placenta, enlarging uterus and increased blood supply. Rapid weight gain is also normal during menopause. The decrease in estrogen levels associated with menopause often results in extra fat or weight gain in the abdominal region and hips.
- Regulatory: The endocrine system is also responsible for regulation of the thyroid gland. This gland is important for making hormones that allow the body to burn calories. As a result, dysfunction in the thyroid gland, especially lack of hormones (hypothyroidism) can result in rapid, unintentional weight gain. The pituitary gland is part of the endocrine system that releases multiple hormones, including one for growth. When too much growth hormone is produced, a condition called acromegaly occurs. Not only do people with acromegaly gain weight rapidly, the bones of the face, hands and feet also increase in size.
- Metabolic: The endocrine system also regulates insulin. In diabetes, there is dysfunction in insulin control that results in high levels of glucose in the blood. Rapid weight gain is often a first sign of diabetes in addition to symptoms such as increased urinary frequency and thirst.
Swelling is the result of fluid buildup (edema) that gets trapped in your body's tissues. Buildup can occur when fluid cannot properly flow and/or drain. Fluid retention throughout the body (anasarca) can result in rapid weight gain that is very noticeable in the extremities, especially the legs.
Cardiac: Problems with the heart and its ability to pump effectively (also known as congestive heart failure) will cause blood to back up in the lower body. This causes excessive pressure in the blood vessels that causes damage and leakage of fluid into the body's tissue.Furthermore, if the veins of the circulatory system are weakened or damaged, swelling will occur in a similar manner.
Kidney: The kidney is a potent regulator of bodily fluid because it is responsible for filtering and clearing the blood. Without the kidney, filtrate such as proteins, electrolytes and toxins can remain in the blood and act as forces that draw fluid out. Fluid retention is a very common and prominent side effect of kidney disease.
Liver: Severe liver disease can also result in fluid retention because of a reduction in protein production by the liver. Low levels of blood protein permit more leakage into the tissues.
The endocrine system also regulates a hormone in the body called cortisol. Cortisol is released by the adrenal glands and is very important for a number of the body's functions, including conversion of nutrients into energy. Sometimes patients have to take medications called corticosteroids for conditions that cause inflammation. Corticosteroids can result in a condition called Cushing's Syndrome. Too much cortisol results in symptoms such as rapid weight gain, a rounded face, and pink or purple stretch marks on your skin.
Top 2 Rapid Weight Gain Causes
1.Acute Kidney Injury
Acute kidney injury is a sudden episode of damage or failure to the kidney. It is common in older adults as well as patients in hospital.
Acute kidney injury requires immediate medical attention to prevent further damage to the kidney and usually results in a hospital stay.
- Top Symptoms:
- nausea or vomiting, abdominal pain (stomach ache), shortness of breath, urinary changes, fatigue
- Symptoms that always occur with acute kidney injury:

Rapid Weight Gain Treatments and Relief
Treatment for rapid weight gain depends on the cause and finding the underlying issue.
Endocrine causes of rapid weight gain that result in hormonal imbalance may be treated by medications that help to normalize the levels. These medications are often used long-term and are specific for the hormones affected.
Cardiac, renal (kidney) or hepatic (liver) causes of fluid retention require evaluation and often multiple tests before treatment can be tailored to the patient's needs.
If medication is the cause of the problem, your doctor will recommend alternative rapid weight gain treatments.
Seek medical attention immediately if you experience symptoms such as:
- shortness of breath
- difficulty breathing
- swollen feet
- heart palpitations
- changes in vision
Such symptoms may signal life-threatening complications of conditions such as diabetes or heart failure that require prompt medical attention.
FAQs About Rapid Weight Gain
Here are some frequently asked questions about rapid weight gain.
Why am I gaining weight but eating the same?
Weight gain can be caused by changes in the functioning of many of the glands in the body as well as changes in caloric consumption that is rarely considered by individuals. Hypothyroidism — as well as excessive amounts of cortisol or overtreated inadequate levels of cortisol — can contribute to unintended weight gain. Additionally, drinks like beer or soft drinks are often not considered food but are very high in calories.
Can depression cause rapid weight gain?
Depression can cause rapid weight gain or rapid weight loss. Depression can slow down metabolism, eliminate motivation to work out, motivation to eat healthy foods, or cause people to self-medicate an absence of positive emotion with food. It is common for severe fluctuations in weight to occur in the setting of the different stages of depression.
What is considered rapid weight gain?
Rapid weight gain is considered problematic if it greater than five percent of an individual's body mass in six months or less with no discernible reason. More often than not, it can be due to changes in diet, water consumption, and retention of water.
Do certain medications lead to rapid weight gain?
Yes, drugs that treat diabetes, bipolar disorder and schizophrenia, depression, or epilepsy can all cause rapid weight gain. Insulin drugs may require a concurrent change in diet to avoid weight gain, and bipolar, depression, and schizophrenia drugs will require monitoring of weight gain and even lipid panels depending on the drug to monitor their effects.
