Stroke's Impact: Can It Take Away Hunger?

Strokes can have a significant impact on a person's appetite, and in some cases, individuals may lose their ability to feel hungry. This can be a result of brain damage affecting the part of the brain that controls senses, including taste and smell. In other cases, individuals may experience a loss of appetite due to depression, which is common after a stroke. Additionally, post-stroke depression can also influence an individual's food preferences, making them less interested in eating. This can lead to malnutrition, which is frequently observed in stroke patients and is associated with poor outcomes.

Loss of appetite after a stroke is not uncommon

Loss of Appetite after a Stroke

It is not uncommon for people to experience a loss of appetite after a stroke. Brain damage can affect a person's appetite and moods, and in some cases, even their sense of taste or smell. This can lead to a decrease in hunger and subsequent weight loss.

Causes

The specific causes of loss of appetite after a stroke can vary. In some cases, it may be due to the location of the stroke in the brain, particularly in the insular cortex, which is associated with regulating food intake. Other factors include:

• Dysphagia (difficulty swallowing)
• Depression
• Medication side effects
• Taste bud dysfunction
• Lack of energy
• Pain and discomfort
• Cognitive deficits
• Anxiety and emotional changes

Management

The management of loss of appetite after a stroke is crucial to prevent malnutrition and ensure adequate nutritional intake. Here are some strategies that can be employed:

• Choosing foods with strong flavours and low in saturated fat and salt, such as citrus fruits, herbs, and spices.
• Opting for colourful and nutritious foods like salmon, carrots, and dark green vegetables.
• Consuming high-calorie foods first during meals.
• Engaging in light exercise, such as walking, to stimulate appetite.
• Addressing any underlying mental health issues, such as depression or anxiety, through therapy or medication.
• Ensuring adequate hydration by thickening liquids if necessary.
• Consulting with a clinical dietitian for nutritional assessment and planning.
• Considering enteral tube feeding or parenteral nutrition if oral intake is insufficient.

Brain damage from a stroke can affect a person's appetite and moods

A stroke can cause brain damage that affects a person's appetite and moods. This can lead to a loss of appetite or an increase in hunger, both of which can have negative consequences for the person's health and recovery.

Loss of appetite

It is not uncommon for stroke survivors to experience a loss of appetite. This can be due to depression, changes in taste or smell, or difficulty swallowing. Post-stroke depression is common and can steal a person's appetite, in addition to causing sadness, anxiety, and trouble sleeping. Damage to the part of the brain that controls senses can also affect a person's sense of taste or smell, making food less appealing. Additionally, stroke survivors may have trouble swallowing, which can make eating difficult and cause them to eat less.

Increased hunger

In some cases, a stroke can lead to an increase in hunger. This may be due to medication side effects or damage to the part of the brain that controls appetite. Increased hunger can lead to weight gain, which can make recovery more difficult. It can also cause emotional breakdowns and distress for the person and their caregivers.

Impact on moods

Brain damage from a stroke can also affect a person's moods. They may experience sadness, anxiety, or a lack of interest in activities they once enjoyed. The person's participation in social activities may decrease, further impacting their mood and recovery.

Management strategies

There are several strategies that can help manage the impact of a stroke on appetite and moods. These include:

• Choosing foods with strong flavours and low in saturated fat and salt, such as citrus fruits, herbs, and spices.
• Opting for colourful foods like salmon, carrots, and dark green vegetables, which are also packed with heart-healthy nutrients.
• Eating high-calorie foods first to ensure adequate energy intake.
• Exercising lightly, such as walking, to increase appetite.
• Addressing mental health concerns with a doctor, who may prescribe antidepressants or recommend talk therapy.
• Making mealtimes social events to ensure the person is eating properly and to provide company.

A stroke can cause dysphagia, or trouble swallowing, which can lead to malnutrition

There are several strategies that can be employed to manage dysphagia and reduce the risk of malnutrition:

• Stick to soft foods that are easier to eat, such as cooked cereal, mashed potatoes, soup, cottage cheese and applesauce.
• Thicken liquids with tapioca, matzo meal, cornstarch or banana/potato flakes to make them safer to swallow.
• See a speech therapist for exercises to strengthen the tongue, lips, throat and mouth muscles, or for neuromuscular electrical stimulation to strengthen the swallowing muscles.
• Use adaptive flatware with larger, thicker handles, or knives with curved blades that can be used with one hand.
• Use plate guards to help scoop food onto utensils.
• Put rubberised pads under plates or bowls to prevent sliding.
• Use adaptive kitchen equipment, such as easy-grip scissors, battery-powered peelers and specialised cutting boards, to aid food preparation.

A stroke survivor may experience an increase in appetite, leading to weight gain and making recovery more difficult

It is possible for a stroke survivor to lose their sense of hunger. This was the case for a 28-year-old Canadian woman who suffered a stroke in the insular cortex region of her brain. However, it is also common for stroke survivors to experience a loss of appetite, which can lead to malnutrition and poor recovery. On the other hand, some stroke survivors may experience an increase in appetite, which can lead to weight gain and also make recovery more difficult.

Increased Appetite After a Stroke

A stroke survivor may experience an increase in appetite, which can lead to weight gain and make the recovery process more challenging. This was the case for a 37-year-old woman who experienced a massive haemorrhagic stroke and subsequently gained weight, making her recovery more difficult. The increase in appetite can be caused by medication or damage to the part of the brain that controls senses, affecting taste and smell.

Managing Increased Appetite

Managing increased appetite after a stroke can be challenging. It is important to consult with a doctor or a specialist stroke rehabilitation team for advice. Some strategies that may help include:

• Dietary modifications: This may involve choosing foods with strong flavours, opting for colourful and nutritious foods, and including high-calorie foods in meals.
• Exercise: Light exercise, such as walking, can help increase appetite and promote recovery.
• Addressing mental health: Depression is common after a stroke and can affect appetite. Seeking support from a therapist or counsellor can help manage depression and improve appetite.
• Meal planning and support: Preparing meals in advance, involving family and friends, and considering local support programs can help ensure the person is eating nutritious meals and receiving social stimulation.

While increased appetite after a stroke can be challenging, there are strategies to manage it. It is important to seek professional advice and support, make dietary modifications, include physical activity, and address any mental health concerns. By doing so, the person can improve their overall health and well-being during the recovery journey.

Nutritional interventions can enhance the recovery of neurocognitive function after a stroke

A stroke can cause brain damage that affects a person's appetite and moods. It can also make it difficult for them to move their muscles and cause sensitivity to pain. These factors can contribute to a loss of appetite and subsequent weight loss. Nutritional interventions are crucial to providing adequate nutrition and preventing malnutrition, which is a common complication after a stroke. Malnutrition can exacerbate brain damage and hinder recovery.

Nutrition plays a vital role in brain recovery after a stroke. Nutritional strategies can provide tube-fed individuals with the necessary nutrients and prevent body wasting, which can lead to poor functional outcomes and prolonged hospital stays. Research has shown that nutritional interventions can enhance the recovery of neurocognitive function in individuals who have experienced an ischemic stroke. Protein synthesis is often suppressed in the ischemic penumbra, and providing protein supplementation has been found to improve recovery. Additionally, nutrition supplementation with B-group vitamins may help mitigate oxidative damage after an acute ischemic stroke. Normalization of zinc intake has also been linked to enhanced neurological recovery in ischemic stroke patients.

The impact of nutritional interventions on functional outcomes in stroke rehabilitation has been the subject of several studies. These studies have highlighted the importance of early nutritional assessment, especially for sarcopenic patients, and the role of energy and protein intake soon after a stroke. Tailored dietary support has been found to be beneficial for muscle mass maintenance and overall functional recovery, particularly in older patients.

In summary, nutritional interventions are crucial in enhancing the recovery of neurocognitive function after a stroke. They can help prevent malnutrition, provide essential nutrients, and improve functional outcomes. Early nutritional assessment and tailored dietary support are key components of effective stroke rehabilitation.
