What are Weight Loss?
Weight loss typically occurs due to a lack of proper nutrition. In the vast majority of animals, it is common and perfectly healthy for their body weight to fluctuate on a seasonal or even monthly basis. That said, after a certain point, a loss of body fat and muscle mass can be considered dangerous and even indicative of a more serious health problem. In ferrets, it does not take much weight loss to cause a noticeable difference in the animal's appearance, owing to their small size. In much the same manner, it does not take a huge loss of weight to provoke some particularly unpleasant symptoms.

Symptoms of Weight Loss in Ferrets
The symptoms associated with weight loss are usually quite pronounced, and become more so as the condition progresses. However, owners should be sure to take action before either the ferret loses too much weight or the underlying condition takes on a level of seriousness that is too great.
As the ferret ceases to obtain the nutrients and vitamins it needs to maintain a healthy outward appearance, one of the first (and most evident) changes will be to the quality of its fur. Owners will typically notice the ferret's coat beginning to lose its normal glossy sheen and take on a more dull and coarse texture. This can happen within mere days of the root problem occurring, so owners should take the opportunity to look for additional symptoms that may otherwise go relatively unnoticed. In some cases, the animal may also begin to shed hair at this stage, particularly from the lower back, stomach and top of the head.
It is common for ferrets suffering from weight loss to have accompanying bouts of nausea. Most animals afflicted with this will typically start to seclude themselves away from other members of the household, preferring to remain in one area of their enclosure. They will also refuse the majority of meals that are offered to them. Additionally, affected ferrets may display some degree of difficulty or pain when swallowing, which could make almost impossible to ingest food. In some cases, they may also be unable to swallow liquids, which will quickly result in the onset of dehydration. This can be especially dangerous, as it can result in both a worsening of the ferret's underlying condition as well as the emergence of additional complications.
In many cases where weight is rapidly lost, the ferret may exhibit a radical change in its daily behavioral patterns and habits. Owners could notice the animal starting to appear far more tired than usual, causing it to abandon its normally highly energetic habits in favor of remaining still for long periods of time. Also, the animal could stay unresponsive even when its owner attempts to interact with it, even ignoring opportunities to play that it would usually take to right away. Commonly, the ferret will choose one particular spot in its enclosure to stay in, moving only to defecate, urinate or attempt to eat or drink.
Ferrets affected by weight loss may also begin to throw up at some point as the condition worsens. At first, this will appear as simple nausea, with the animal becoming unwilling to eat or be touched and choosing to isolate itself. Eventually, the ferret may begin to vomit, usually in an attempt to expel toxins by voiding the contents of its digestive system. Unlike normal regurgitation of indigestible material, vomiting due to other causes will be sustained over a period of hours or even days. This means that the ferret will be at significant risk of dehydration.
Abdominal pain will commonly accompany most cases of pronounced weight loss. This is because many of the illnesses that cause the condition will have a direct impact on the health and integrity of the digestive system itself. Commonly, the ferret can be expected to avoid physical activity as much as possible, preferring instead to remain still so as not to put unexpected pressure on the abdomen. This may force them into maintaining an unusual posture for long periods of time, such as sitting upright with its forelimbs held away from the chest. The ferret may also steadily become more and more defensive, exhibiting behavior ranging from an unwillingness to be touched, to outright aggressiveness towards anyone who attempts to disturb them.
Causes of Weight Loss in Ferrets
The most common causes of weight loss in ferrets are stomach ulcers, gastrointestinal disorders, liver disease, poisoning, and cancer. Stomach ulcers occur when the lining of the stomach is damaged and stomach acid prevents the wound from properly healing. This happens most frequently when foreign objects are ingested and cut into the tissues of the digestive tract. This ulcer will create a significant amount of pain and discomfort for the ferret, causing a long-term impact on their willingness to eat, thereby resulting in a loss of weight. Similarly, many common poisons found in plants and venomous animals contain compounds whose main purpose is to irritate and damage the tissues of the stomach, provoking nausea and vomiting. Liver disease will also cause much stomach upset due to the body's inability to filter poisons out of the bloodstream as the liver ceases to function correctly. Cancers, in not just the digestive system itself but also many associated organs (such as the kidneys, liver, and pancreas), can cause a considerable amount of difficulty digesting food, and can often lead to a dramatic loss of body mass.
Diagnosis of Weight Loss in Ferrets
Once the ferret has been brought into the veterinary clinic, they will be subjected to a full physical examination. This will give the vet an opportunity to check for additional symptoms that could betray the presence of an underlying health problem. They will also take samples of urine, feces, and bile in order to try and determine the cause of the weight loss. Also, imaging of the digestive tract using either an endoscope or ultrasound scan can reveal direct damage to the stomach (such as ulcers) or growths and tumors within the abdominal cavity that may have an effect on the ferret's ability to consume and digest food. In cases where cancer is detected but not located, exploratory surgery of the chest cavity may be performed in order to find the tumor.
Treatment of Weight Loss in Ferrets
Oftentimes, when a ferret has become dehydrated, the first action the vet will take is to start the animal on fluid therapy, which is the process of intravenously putting more liquids into its body. This will both rehydrate the animal and provoke urination, which may help flush contaminants out of its blood supply. Stomach ulcers are mostly treated by a course of antibiotics, which will allow the lesion in the stomach lining to heal. Liver disease meanwhile, may require specific drugs to restore normal organ functionality if the condition has reached its advanced stages. Cancer has several different treatment methods available which are exclusive to the type and quantity of tumors within the ferret's body and will require further testing after the initial diagnosis. In cases of poisoning, however, the condition is most often left to run its course with the ferret under close observation, as the effects are usually temporary.
Recovery of Weight Loss in Ferrets
Ferrets on courses of antibiotics may take several weeks to properly recover, due to the necessarily extended duration of a course of such drugs in order to prevent a resurgence of the bacteria. Animals with liver problems may require longer, depending on the issue, whilst others may need drugs to be administered regularly for the rest of their lives. The vet will usually want to schedule a series of follow-up visits in order to make sure that the ferret is recovering well and to perform further test if necessary (such as if cancer is present). In all cases, it may be somewhat difficult for the ferret to adjust back to having a normal diet again, so the vet will most likely recommend feeding them fairly bland and easily digestible meals for a week or two in order to lessen the stress on their stomach.
