What is Hypoglycemia?
Low blood sugar levels. This can be fatal as the brain depends on sugar for energy. It is usually caused by diabetes medications, but can also be caused by hormone disorders and insulin overproduction.
Typical Symptoms of Hypoglycemia
- Taking insulin or other diabetic drugs
- Symptoms improve with meals
- Seizure
- Fine tremors of the hands or fingers
- Difficulty speaking, performing tasks, or recognizing things
- History of stomach surgery
- Cold sweat
- Heart pounding
Diagnostic Questions for Hypoglycemia
Your doctor may ask these questions to check for this disease:
- Are you taking diabetic medications?
- Does eating improve your symptoms?
- Have you experienced any seizures?
- Do you experience fine tremors in your hands or fingers?
- Have you been experiencing difficulty speaking, performing tasks, or recognizing things?
Treatment of Hypoglycemia
This condition is first managed by consuming sugar quickly - options include candy, honey, table sugar, or sweet drinks. In severe cases where a patient is unconscious, a sugar-containing drip can be given via a needle in the vein. It is important to find the reason for low blood sugar, to prevent it from happening again.

Q.
Why Am I Sleepy After Eating? 5 Health Warnings for Women 65+
A.
There are several factors to consider; in women 65+, feeling sleepy after eating is often from normal digestion or large, carb-heavy meals, but it can also warn of blood sugar swings, post-meal low blood pressure, thyroid problems, or heart and circulation issues. If drowsiness is sudden, intense, or comes with dizziness, shakiness, chest discomfort, shortness of breath, or fainting, speak with a doctor promptly and seek urgent care for severe symptoms. See the complete guidance below for practical meal fixes, key warning signs, and when to get tests that can affect your next steps.

Q.
Blood Sugar Over 65: Preventing Spikes & Senior Diabetes
A.
After 65, blood sugar can swing due to reduced insulin sensitivity, less muscle, slower digestion, medications, and routine changes; typical goals are fasting 80 to 130 mg/dL and after meals below 180 mg/dL, personalized to avoid both highs and dangerous lows. Steadier control comes from balanced higher fiber meals paired with protein and healthy fats, safe activity like walking and light strength work, medication reviews, better sleep and stress management, and right-sized monitoring; there are several factors to consider, including subtle low sugar symptoms, when to call a doctor, which drugs can affect readings, and how often to check, so see the complete guidance below.

Women’s Glucose Guide: Balancing Blood Sugar and Health
A.
Balanced glucose supports women’s energy, mood, hormones, heart health, and pregnancy, and it naturally shifts with the menstrual cycle, pregnancy, perimenopause, menopause, and PCOS. There are several factors to consider; see below to understand key symptoms of highs and lows, everyday habits for stable blood sugar, who should get tests like fasting glucose, A1C, or tolerance testing, and urgent warning signs that should guide your next healthcare steps.

Why do I get low blood sugar even when I eat?
A.
You might experience low blood sugar after eating due to a condition called reactive hypoglycemia, where your body releases too much insulin after meals. See below to understand more.
