As we head into July, the warmer weather can increase the risk of dehydration and may also affect how certain Parkinson’s symptoms show up day to day. The good news is that nutrition and hydration can play a helpful role in managing common symptoms like fatigue, digestive issues, changes in taste and smell, and shifts in body weight. Let’s look at some simple ways to support your well-being through food and fluids this summer.
1. Fatigue and Energy Levels
Fatigue is a common experience with PD, and what you eat can make a real difference in how energized you feel. Choosing complex carbohydrates like whole grains, legumes, and starchy vegetables helps keep blood sugar steady. Pair these with healthy fats and protein sources such as nuts, seeds, tofu, or avocado to support sustained energy throughout the day. Snacks like peanut butter with fruit or whole grain toast with hummus are also great ways to keep your energy up between meals.
Staying hydrated is just as important. Even mild dehydration can leave you feeling more tired. Be sure to drink water regularly and enjoy water-rich foods like cucumbers, citrus fruits and melons (especially on hotter days).
2. Digestive Health and Constipation
Digestive discomfort like constipation and bloating is very common in PD. Adding more fiber to your meals can help things move more smoothly. Some of the best sources include fruits, vegetables, whole grains, legumes, oats, and ground flaxseeds. Fermented foods like yogurt with live cultures, sauerkraut, or kombucha may also be helpful for gut health.
Fiber only works well when paired with enough fluids, so aim to drink at least six to eight cups of water or other hydrating beverages each day. You may need more when it’s hot out or if you’re more active!
3. Changes in Taste and Smell
Many people with PD notice that food doesn’t taste or smell quite the same. This can make meals less enjoyable or lead to a smaller appetite. To help bring meals back to life, try using flavorful herbs and spices, or add a splash of lemon juice or vinegar to brighten the taste. Mixing up textures and serving food at different temperatures can also make a meal more interesting. And don’t underestimate the power of presentation - colorful, visually appealing plates can help spark interest in eating.
If drinking plain water is unappealing, try infusing it with slices of fruit, fresh herbs, or cucumber to add natural flavor.
4. Weight Changes
Unintended weight changes (either loss or gain) are also common with PD. If you’re losing weight without trying, focus on eating smaller meals more often and include calorie-dense, nourishing ingredients like nut butters, olive oil, avocado, and smoothies made with milk or plant-based alternatives, fruits, and protein sources.
If you’re working to manage weight gain, choose high-fiber meals that are satisfying without being too heavy. Options like hearty vegetable soups, large salads with beans or lentils, and roasted vegetables can offer balance. Water-rich foods may also help you feel full and refreshed without adding extra calories.
5. Managing Orthostatic Hypotension
Many people with Parkinson’s experience neurogenic orthostatic hypotension, a condition where blood pressure drops suddenly when standing up. This can lead to dizziness, lightheadedness, or even fainting. Staying well hydrated is key to helping manage these symptoms, especially in hot weather when fluid loss can happen more easily. In addition to drinking plenty of water, some people benefit from including fluids with added electrolytes, such as low-sugar electrolyte drinks, coconut water, or a homemade mix with a pinch of salt and a splash of citrus juice. These help the body hold on to fluids more effectively and support stable blood pressure.
Be sure to speak with your healthcare provider about whether electrolyte drinks are right for you, especially if you’re managing blood pressure with medication.
In SummaryWhat you eat and drink can have a big impact on how you feel, especially during the warmer months. Whether you’re managing fatigue, digestive changes, appetite shifts, weight fluctuations, or blood pressure concerns, thoughtful nutrition and hydration can support your daily well-being. If you’re looking for more tailored support, don’t hesitate to reach out to your healthcare provider or a registered dietitian to make sure you're meeting your individual needs this summer!
