Spironolactone is a medication commonly prescribed for various conditions, including high blood pressure, heart failure, and hormonal imbalances like those seen in polycystic ovary syndrome (PCOS).
While it is a highly effective drug, there have been claims and concerns about spironolactone causing weight gain.
In this blog post, we will dive into the topic to explore the truth behind these claims and understand whether spironolactone truly leads to weight gain.
Spironolactone is a diuretic, which means it helps the body enhance urine production to rid itself of excess fluid. It also works as an aldosterone antagonist, blocking the effects of the hormone aldosterone, which regulates fluid and electrolyte balance. By doing so, spironolactone helps reduce fluid retention and lower blood pressure.
Does Spironolactone Cause Weight Gain?
The topic of weight gain associated with spironolactone has been a subject of debate and confusion among patients and healthcare professionals. However, it’s important to note that weight gain is not a direct side effect of the medication itself.
Instead, any weight changes observed may be attributed to other factors, including individual responses and underlying medical conditions.
Fluid Retention: Some individuals may experience a reduction in fluid retention while taking spironolactone, which could lead to a decrease in weight. Conversely, discontinuing the medication may cause fluid retention and a temporary increase in weight.
Hormonal Effects: Spironolactone is commonly prescribed for conditions such as PCOS, where weight gain is a symptom. By targeting hormonal imbalances, spironolactone may help in managing weight-related issues associated with conditions like PCOS.
Appetite and Metabolism: While spironolactone does not directly affect appetite or metabolism, some individuals may notice changes in their appetite or eating habits due to the medication’s impact on hormone regulation. These changes in appetite could contribute to weight fluctuations, but it’s important to note that this varies from person to person.
Individual Variations: It’s essential to consider that everyone’s body reacts differently to medications. Some individuals may experience weight gain while taking spironolactone. Still, it’s crucial to evaluate other factors, such as lifestyle changes, dietary habits, or concurrent medications that may contribute to weight fluctuations.
Consulting a Healthcare Professional
If you have concerns about weight changes while taking spironolactone, it is crucial to consult your healthcare professional. They can evaluate your particular circumstances situation, evaluate any potential underlying causes, and determine the best course of action. It’s important not to make any abrupt changes to your medication regimen without professional guidance.

Spironolactone and Water Retention
One of the main reasons why spironolactone is prescribed is to reduce water retention, or oedema, which can occur in various conditions. Water retention is caused by an imbalance of fluid and electrolyte balance within the body, potentially resulting in swelling, bloating, and weight gain.
By blocking aldosterone, spironolactone can promote the excretion of excess fluid and sodium, which can help reduce water retention and its associated symptoms.
However, it’s important to note that not everyone who takes spironolactone will experience water retention or oedema. Some people may notice a decrease in their weight due to the loss of excess fluid.
Additionally, spironolactone is not a diuretic, which means that it does not promote excessive urination or dehydration. Therefore, the idea that spironolactone causes weight gain by increasing water retention is not entirely accurate.
Spironolactone and Hormonal Changes
Another factor that can influence body weight while taking spironolactone is hormonal changes. Spironolactone is commonly used to treat conditions that involve hormonal imbalances, such as acne, PCOS, and hirsutism. Spironolactone reduces androgen effects, decreasing sebum production, hair growth, and related symptoms in these conditions.
However, androgens also play a role in regulating body weight and metabolism. Studies have shown that women with PCOS or other androgen-related conditions may have a higher risk of insulin resistance, weight gain and metabolic syndrome. By reducing androgen levels, spironolactone may help improve these metabolic parameters and promote weight loss.
On the other hand, some studies have suggested that spironolactone may also have negative effects on lipid metabolism and insulin sensitivity, which could lead to weight gain or other metabolic problems in some individuals. However, these effects are not consistent across all studies, and more research is needed to clarify the mechanisms and implications of spironolactone on body weight.
Common Misconceptions About Spironolactone and Weight Gain
Despite the lack of conclusive evidence on the link between spironolactone and weight gain, some misconceptions and myths persist in the public and medical communities. Here are a few of the most typical ones:
- Spironolactone causes water retention and bloating: As discussed earlier, spironolactone can reduce water retention and oedema in some people, although not all.
- It slows down metabolism: There is no evidence to support the claim that spironolactone affects metabolic rate or energy expenditure in a significant way.
- Spironolactone increases appetite or cravings: While some people may experience changes in appetite or taste while taking spironolactone, there is no evidence that it directly stimulates hunger or food intake.
- It always causes weight gain: As with any medication, the effects of spironolactone on body weight can differ based on individual factors like genetics, lifestyle, and underlying health conditions.
While claims of spironolactone causing weight gain have circulated, it’s essential to separate fact from fiction. Spironolactone itself does not directly cause weight gain, but individual responses and underlying factors may contribute to weight fluctuations.
Consult your healthcare professional for concerns about weight changes or side effects while taking any medication. They are best equipped to evaluate your situation and provide appropriate guidance to ensure your overall well-being.
