What Can Cause a Lack of Appetite?

Common Causes of Lack of Appetite You Should Know

Loss of appetite or anorexia occurs because of several conditions, such as the common cold or an infection. Patients suffering from malnutrition or weight loss can experience loss of appetite, which can become serious if left untreated.

What are the Possible Causes of a Lack of Appetite? 

Various physical and medical conditions can impact your desire to eat or your feeling of hunger. These are some of the factors that may cause a loss of appetite:

• Bacterial or Viral Infections : Any bacterial or viral infection can cause a temporary loss of appetite. Our immune system utilises additional nutrients to eliminate pathogens and does not get more nutrients to fill the gap. This results in metabolic changes, leading to symptoms like nausea or loss of appetite.
• Psychological Causes : Different psychological issues, such as stress, feelings of sadness, and grief, may lead to short-term appetite loss. Other conditions, such as anxiety, chronic stress or long-term depression, can also cause loss of appetite. Frequent suffering from eating disorders, like anorexia nervosa, may also lead to appetite loss. 
• Medical Conditions : Various medical conditions may lead to a decreased appetite, such as kidney failure, type 2 diabetes, hypertension, hepatitis, and hypothyroidism. Apart from these, colon, stomach, or pancreatic cancers can cause loss of appetite at later stages. Additionally, treatment like chemotherapy may decrease your appetite.
• Medications : Antibiotics or other related medicines, such as antidepressants, immunomodulators, antipsychotics, or blood pressure medication, can reduce your appetite. Other than these, frequent use of nasal decongestants can contribute to a lack of appetite. Most of these antibiotics interfere with your bodily functions and neurotransmitters.  

What are the Side Effects of Appetite?

Prolonged lack of appetite can cause weight loss and malnutrition. Loss of calorie intake and electrolytes can affect your metabolic and other physiological processes, leading to a decrease in function and effectiveness. If lack of appetite persists without treatment, it can cause severe health problems.  

How Do You Treat Not Feeling Hungry?

The treatment of a lack of appetite depends on its cause. Your doctor may conduct some diagnostic tests to understand the causes of this issue and will provide treatment to resolve it. Common treatments include:

• Consuming small and sufficient meals regularly throughout the day.
• Consult with your healthcare provider to manage any underlying illnesses or infections.
• Take certain medications like megestrol or dronabinol to stimulate your appetite.
• In case of serious complications, take IV nutrient supplements containing minerals and liquid vitamins.
• Consult with a mental health specialist regarding your irregular eating habits.
• Try to change the type or dosage of medicines you are taking regularly after consulting with your healthcare provider.
• Consult with a dietitian to manage your diet and introduce supplements or vitamins into your daily diet.
• In case of any toothache or pain in the gum, consult a dentist immediately, as these can trigger a lack of appetite.  

If your appetite loss is not resolving even after complete treatment, it can indicate some underlying issues.   

What Should I Eat if I Have a Poor Appetite?

Poor appetite can cause muscle loss and chronic tiredness due to a lower supply of nutrients in the body. Vital minerals are crucial to carry out metabolic functions, and additional intake of lower amounts of minerals can also affect your immune system.

Thus, here we will discuss some foods which you can eat if you have a poor appetite. These include:

• Fruit : Fruits provide essential nutrients, fibres, and a certain amount of water, which can be detrimental to your health. Eating fruits regularly can improve your appetite if you add proteins or carbohydrates to your diet.
• Toast : Toast is one of those foods which is highly digestible for anyone. Additionally, it is a common staple food across the globe. Eating whole-grain bread along with toppings of a nutritious fat source like avocado or peanut butter can nourish your body with sufficient calories.
• Soups : Soups are the best alternative supplement to keep yourself hydrated. If you can prepare them correctly, they can be an excellent source of calories, such as protein, fats, and carbohydrates. If possible, try to eat soups along with a source of vegetables, protein, and whole grains.
• Smoothies : Smoothies offer a nutrient-dense source of calories in small portions. It will be excellent if you can add various vegetables and fruits to pack more nutrition into it. Additionally, you can add a protein or fat source, such as peanut butter or avocado.

Apart from these, you can eat yoghurts with high-fat content, oatmeal, or eggs. Greek yoghurts can add extra fats and probiotics, which can improve the gut microbial flora. Try oatmeal with milk to add calcium and potassium.
