Dear lybrate-user,
Feeling tired and lack of energy can be seen in many cases like low Haemoglobin levels, low blood pressure, diabetes digestion issues, infections or fever etc. It may be due to simple lifestyle issues like untimely food, lack of proper sleep/ oversleep, lack of physical activity etc. You can correct all your daily habits like food (eat balanced food, better avoid processed ones), sleep minimum 6 hours a day, drink adequate amount of water and indulge in physical activities. I believe your problems may be solved.
Following are some of the early symptoms of diabetes, but a presence of few symptoms doesn't mean that you have diabetes. It is always better to consult a doctor for confirmation, before getting unnecessarily tensed.
1. Increased Sweating may be accompanied by body odour
2. Tendency to Urinate frequently
3. Excessive thirst 4. Excess Hunger
5. Wound/ sores takes a long time to heal
6. Feels exhausted and fatigue 7. Dry mouth and itchy skin
8. Burning sensation of palms and feet
9. Blurred vision
I would like to stress again that if you find any of theses symptoms, it has no meaning that you suffer from diabetes. It may be due to a variety of issues.
