Symptoms of hyperlipidemiaHyperlipidemia is a condition in which there are elevated fat levels, especially cholesterol and triglycerides, in the blood. It can increase the risk of cardiovascular disease. in dogs can be subtle and non-specific. Often, the condition is discovered by chance during blood tests performed for other reasons. Nevertheless, there are some signs that pet owners can look out for.
A common symptom is a sluggish or lethargic behavior. Dogs may be less active or tire more quickly. This often goes hand in hand with weight gain, although the appetite may be normal or even increased.
In some cases, skin problems such as oily skin or hair loss may occur. In more serious cases, neurological symptoms can occur, such as seizures or behavioral changes, especially if the hyperlipidemiaHyperlipidemia is a condition in which there are elevated fat levels, especially cholesterol and triglycerides, in the blood.

Therapy
The therapy for hyperlipidemiaHyperlipidemia is a condition in which there are elevated fat levels, especially cholesterol and triglycerides, in the blood. It can increase the risk of cardiovascular disease. in dogs depends on the underlying cause. In primaryPrimary refers to the first or original cause of a disease or condition, as opposed to secondary causes or symptoms that develop from it. hyperlipidemiaHyperlipidemia is a condition in which there are elevated fat levels, especially cholesterol and triglycerides, in the blood. It can increase the risk of cardiovascular disease., which is genetic, treatment focuses primarily on dietary changes and weight control. A low-fat diet can help lower lipid levels in the blood.
For secondary hyperlipidemiaHyperlipidemia is a condition in which there are elevated fat levels, especially cholesterol and triglycerides, in the blood. It can increase the risk of cardiovascular disease., treating the underlying disease is crucial. For example, a dog with hypothyroidism may receive thyroxineThyroxine, also known as T4, is a thyroid hormone that regulates important functions in metabolism, growth, and development in dogs and cats. An over- or underproduction of thyroxine can lead to thyroid diseases. supplements to normalize thyroid function, which in turn can stabilize lipid levels.
Medications can also be used to directly lower lipid levels. Omega-3 fatty acids and certain fibrates are known to lower triglyceride levelsTriglyceride levels are a measure of the amount of triglycerides (certain fats) in your blood. Deviations from normal levels may indicate metabolic disorders or diseases.. The veterinarian may also prescribe medications that reduce fat absorptionAbsorption refers to the uptake of substances by living cells or tissues.
