Reasons Why Your Hamster is Losing Weight

Low-Quality Hamster Food

It starts with the food going into your hamster’s digestive system.

If your hamster isn’t eating enough, it may have to do with the type of food it is getting. In fact, there are times when a hamster will eat loads of food but isn’t going to get enough nutrients out of them on a per serving basis.

This means you have to take a step back and analyze what you are feeding your hamster.

One of the worst mistakes a hamster owner can make is to feed low-quality food to the pet. This is going to have a detrimental impact on their health and could even cut into their lifespan depending on how poorly formulated the food is!

Be smart about what you are giving to the hamster. The food should be well-made, organic, and safe for your breed. This is the only way to make sure the hamster doesn’t end up eating something that shouldn’t be going into its digestive system.

When it is time to make a positive change, this is one of the easiest ones a hamster owner can make. Simply go out and buy good hamster food for your hamster.

Why Is My Hamster Losing Weight

Small Portions

Along with buying the best hamster food for gaining weight, you also have to think about how much your hamster is eating throughout the day.

This is all about understanding your hamster and its needs. Sometimes, you are simply not going to be putting enough in the food bowl leading to weight issues.

You will have to take the time to measure the hamster food, control the servings, and make sure the portions are well-sized.

Increasing portion sizes can be a good starting point when there is a noticeable decline in a hamster’s weight.

To get started, take the time to measure the servings for a day. You are going to see how many calories the hamster is eating daily. Once you have this figure, it’s time to start increasing the number of calories the hamster is consuming each day by 200-300.

This is going to be a good starting point and will let you make adjustments over time. Give it a few weeks (assuming your hamster’s health isn’t declining rapidly!) and then continue to increase the portions until their weight goes up.

Remember, you don’t want to overdo things! There is no reason to make your hamster overweight by overdoing the increases.

Gradually increasing the number of calories your hamster eats daily is more than enough.

Underlying Health Issues

This is one of the more concerning causes of hamsters losing weight.

If your hamster is starting to decline in terms of energy levels then this may be the leading issue. In general, a hamster can start dealing with health-related trouble as they grow older. If you have an aging hamster then this has to be where your mind goes first.

When there are health-related issues, take the time to visit your vet as soon as you can.

The vet is going to take a complete look at your hamster, analyze what is going on, and come up with an underlying diagnosis. This is essential to ensure your hamster is being treated effectively and can get back to living as soon as possible.

Ignoring these health issues and assuming they will go away is the wrong approach to take!

You have to do your due diligence and it is ALWAYS better to be safe rather than sorry. Unfortunately, many hamster owners don’t do this and end up having to deal with their beloved pet passing away.

Please take the time to visit a vet and see what they have to say before making adjustments. This will shed light on what has to be done and which changes will work.

Nutrient Deficiencies

Not having enough nutrients to eat is a major concern for the average hamster.

When the hamster isn’t getting enough nutrients through its food, there are going to be signifiant related issues that will start to pop up.

As a result, you have to make sure to see what the hamster is eating and only give it high-quality hamster food.

If you are not giving the hamster safe food, how is it going to remain healthy? It is almost impossible to ensure the hamster remains healthy when its diet is poor.

A vitamin B deficiency is a known medical concern among health experts and can become a lingering cause of weight loss in hamsters.

If necessary, you should also take the time to include high-value supplements for your hamster such as Oasis Vita-Drops High Potency Multi-Vitamins. These multi-vitamins are going to be a great way to help your hamster gain weight and stay fit.

Excessive Physical Activity

An underrated factor that has to be kept in mind would be your hamster’s physical activity throughout the day, week, month, and year.

How much time is your hamster spending inside a hamster ball or a hamster wheel? Is it more than normal or is it something that has not been as high as it should be?

This is an important detail to think about because it is possible for your hamster to overexercise. While the average hamster can handle consistent movement, this doesn’t mean it has an unlimited well of energy to tap into! The hamster is going to burn calories, so you have to be sure it isn’t burning too much on a per day basis.

If you want to test this particular cause, take a step back on the physical activity for your hamster.

This doesn’t mean you take away everything! The goal is to simply reduce the amount of time spent inside a hamster ball or only letting them work out on a hamster wheel for set periods. This is going to vary from situation to situation.

When you start asking “Why is my hamster losing weight?” this is a good detail to think about. Sometimes, it can be the exact opposite where your hamster stops using its hamster wheel. If that is the case then you know it may have something to do with a health issue.

Your goal has to be to continually analyze how much physical activity your hamster is getting. This is one of the best ways to recognize patterns and start making adjustments immediately. When you do make adjustments, do it gradually so your hamster stays as healthy as it needs to be.
