If you\u2019re one of the 47 million Americans who take a medication to treat high cholesterol, you may have heard of<\/span> pravastatin<\/span><\/a>, a statin drug that is approved by the Food and Drug Administration (FDA) to lower bad cholesterol levels and help prevent heart disease.<\/span><\/p>\n

While pravastatin, also sold under the brand name Pravachol, does not directly cause weight gain, some people may notice slight changes in their weight after starting the medication. These changes are often due to indirect factors rather than the drug itself.\u00a0<\/span><\/p>\n

Can pravastatin cause weight gain?<\/span><\/h2>\n

Weight gain is not a side effect of pravastatin. It\u2019s a common myth that statin medications make you pack on the pounds. However, research shows it\u2019s not true for most people with no preexisting health conditions.<\/span><\/p>\n

Previously, it was thought that taking statins decreased <\/span>leptin production<\/span><\/a> (a hormone that suppresses hunger and promotes satiety), increasing appetite. Clinical trials have proven these medications don\u2019t slow your metabolism or change <\/span>leptin levels<\/span><\/a>. Yet, pravastatin can indirectly influence weight gain in a few ways.\u00a0<\/span><\/p>\n

Muscle weakness\u00a0<\/span><\/h3>\n

Statins \u201ccan sometimes lead to muscle fatigue or weakness, making staying active more challenging,\u201d explains <\/span>Pamela Tambini<\/span><\/a>, MD, a board-certified internist and Medical Director at Engage Wellness. Muscle pain or fatigue is one of the most common side effects associated with statin use. However, it is often alleviated by reducing the dose of the medication<\/a> or switching to a different statin medication.\u00a0<\/span><\/p>\n

HMG-CoA reductase inhibitors<\/span><\/a>, the class of medication to which pravastatin belongs, can cause <\/span>muscle weakness or fatigue<\/span><\/a>, which can reduce how much you exercise. The age-old rule applies here: If you become less active, you will likely burn fewer calories, which can lead to weight gain.\u00a0<\/span><\/p>\n

Fatigue<\/span><\/h3>\n

Even though statins don\u2019t inhibit metabolism function, <\/span>studies indicate<\/span><\/a> that they reduce coenzyme Q10 (CoQ10), an energy metabolism component. This can lead to minor fatigue and reduced energy usage, indirectly contributing to weight gain.<\/span><\/p>\n

Insulin resistance<\/span><\/h3>\n

For people with Type 2 diabetes, statins can potentially increase <\/span>blood sugar<\/span><\/a> and <\/span>insulin resistance<\/span><\/a>. Insulin resistance is linked to <\/span>excess belly fat<\/span><\/a> and difficulty losing weight. However, the benefits of statin use often outweigh the risks of these side effects.\u00a0<\/span><\/p>\n

Dietary changes<\/span><\/h3>\n

Before starting statin therapy, people may try to reduce cholesterol naturally by losing weight or eating a balanced diet. It\u2019s possible after starting pravastatin, some might <\/span>unconsciously relax<\/span><\/a> their diet, assuming that the medication will counterbalance their eating habits, Dr. Tambini says. In other words, people feel like taking medication for cholesterol means they don\u2019t have to watch what they eat and may consume high-fat, high-calorie foods. For that reason, it\u2019s important to focus on eating a healthy diet and prioritizing exercise.<\/span><\/p>\n

Age<\/span><\/h3>\n

It\u2019s relatively normal to experience <\/span>weight redistribution<\/span><\/a> as you get older. Additionally, statin use tends to <\/span>increase with age<\/span><\/a>, from 17.4% in adults aged 40\u201359 to 43.3% in adults aged 60\u201374 and 47.6% in adults aged 75 and older. \u201cIf belly fat increases after starting pravastatin, it is more likely due to lifestyle changes, diet, or natural aging rather than the medication itself,\u201d Dr. Tambini says.<\/span><\/p>\n

While the impact of statins can vary from person to person, the general medical consensus is that weight gain while taking pravastatin is likely <\/span>related<\/span><\/i> to the medication but not <\/span>caused<\/span><\/i> by it. In fact, many individuals taking pravastatin do not notice any changes in their weight or activity levels.\u00a0<\/span><\/p>\n

Does pravastatin make it hard to lose weight?<\/span><\/h2>\n

Reduced ability to lose weight is not a side effect of pravastatin. The most common side effects of statins are muscle pain, nausea, vomiting, or diarrhea. However, some who take statins report difficulty losing weight. In many cases, this is due to decreased activity, insulin resistance, dietary changes, or natural aging. Luckily, many of these causes are easily managed with traditional lifestyle interventions and weight management techniques.<\/span><\/p>\n

Tips for managing your weight on pravastatin<\/span><\/h2>\n

According to Dr. Horsham, the first rule is, \u201cDo not overeat with a false sense of security due to being on a statin. This is what usually causes weight gain.\u201d While providers cite this overconfidence as the most common reason for weight gain on pravastatin, the good news is that the recommendations for maintaining a healthy weight while taking this medication don\u2019t differ substantially from <\/span>the recommendations<\/span><\/a> you might already be familiar with.<\/span><\/p>\n
