Sometimes the symptoms of suboptimal nutrition are not as obvious as dramatic changes in weight or physical appearance. Headaches and light-headedness are common problems that may be caused by underlying dietary habits. You may not even realize how very small changes in your usual intake can influence the way you feel on a regular basis. Paying attention to a few common trigger foods can help you pinpoint the cause of these problems.
Caffeine
Although a morning coffee can give you an energy boost, overdosing on caffeine can cause drowsiness, light-headedness and weakness. Caffeine is found mainly in coffee drinks, teas, chocolate and over-the-counter headache medications. Depending on your response to this drug, it may be beneficial or detrimental for reducing light-headedness and headache symptoms. If you normally have a lot of caffeine during the day, you are likely desensitized to its effects and may experience unpleasant withdrawal symptoms. If you think caffeine could be the route of your negative side effects, try weaning yourself off gradually and withholding conclusions until withdrawal symptoms have subsided.
Blood Sugar
Even if you do not have diabetes, going without food can cause a dip in blood sugar levels associated with light-headedness. Some people are more vulnerable to this effect. If you feel sudden shakiness and blurred vision from not eating after three or more hours, having a quick carbohydrate snack can instantly restore your strength. Carry crackers or hard candy with you as a precaution. Consuming three regular meals a day along with a few healthy snacks can prevent this problem. Have protein and fiber with every meal to slow blood sugar release and keep you feeling steady.
Hydration
Headaches are a major symptom of dehydration. Even if you do not feel thirsty, it is important to drink water regularly throughout the day. The general recommendation is eight to 10 glasses of water, but your needs vary based on activity level, body weight, age and environmental temperatures. You can also get water from foods, including soups and fresh fruit. If you have a headache, try drinking a glass of water to see if helps.
Anemia
Anemia is the impaired ability of red blood cells to carry oxygen to tissues throughout the body, including your brain. Slight anemia can make you feel lethargic and have trouble concentrating. Talk to your doctor about a blood test to see if anemia is putting a damper on your energy levels. Poor intake or absorption of iron, vitamin B12 or folate can all contribute to anemia. Consuming a varied diet and keeping up with regular physical activity are your best defenses against headaches and light-headedness. If these symptoms are getting in the way of your normal routine, have a thorough check-up to determine the cause.
