How Sweet Is Your Blood?


Being a primary care physician, I get to see different medical problems affecting the entire age range. Lately, I noticed that I am seeing more and more cases of adult onset diabetes. This prompted this post for the information of everyone.

We all have occasional episodes of high blood sugar. The most common culprits include:
  • Eating too much
  • Exercising less than you planned to
  • Physical stress, such as a cold, infection or the flu
  • Emotional stress, such as family conflict or workplace challenges
These bouts of hyperglycemia however should be temporary and should not cause symptoms that will become persistent. These symptoms include:
  • Frequent urination
  • Increased thirst
  • Dry mouth
  • Blurred vision
  • Fatigue
  • Nausea
If these are felt, a fasting blood sugar (FBS) should be taken. The normal reference values are 3.89 – 5.84 mmol/l or 70 – 105 mg/dl.

If the FBS is high, we need to have an action plan to get it down. If we think the high level is because we ate more than usual or splurged on dessert, then following it with a walk or some exercise should help to lower it.

If the high is from stress, let's do our best to take a breather and try to relax. Of course, this is easier said than done, but lowering our stress is important to help lower your blood glucose levels.

After we've taken all action to make sure that our blood glucose level has gone down, let's have our FBS taken again. If the blood glucose levels is still higher than usual, it's time to consult our doctor.

Know that long periods of hyperglycemia can damage our nerves, blood vessels and various organs. Left untreated, high blood sugar may turn into diabetic ketoacidosis or diabetic hyperosmolar syndrome — both life-threatening conditions.

There are a number of risk factors which significantly increase the likelihood of having an adult onset diabetes. If you are positive for any one of these, just like me, be more diligent and conscious of the tell-tale signs and symptoms mentioned above.
  • a family history of Type 2 Diabetes or heart disease
  • being overweight or obese
  • being aged 45 or older
  • suffering from hypertension (high blood pressure)
  • belonging to a high-risk ethnic group, namely African-Americans, Asian-Americans, Latinos or Pacific Islanders
  • being "apple-shaped" rather than "pear-shaped," meaning that excess weight gathers around your waist, rather than your hips
  • if female, suffering from Gestational Diabetes while pregnant or giving birth to a baby weighing more than 9 lbs
  • eating an excess amount of carbohydrates
  • leading a sedentary lifestyle with little or no exercise
  • being recently diagnosed as suffering from Insulin Resistance

Abdominal Epilepsy?

The other day, I encountered an uncommon medical diagnosis, abdominal epilepsy. Maybe I was absent when this was taught in med school or maybe it was mentioned but it just didn't register in my memory bank. Anyway, for those colleagues who haven't heard of this as well, here's what I found out about it, so that next time you are faced with a weird abdominal pain, you will think of abdominal epilepsy as a differential. There are many medical causes of abdominal pain; abdominal epilepsy is one of the rare causes. From a medical perspective, the term epilepsy refers not to a single disease, but to a group of symptoms with numerous causes. The common factor in all forms of epilepsy is an excessive electrical excitability of the brain. The increased excitation is called a seizure and may manifest as a partial or total loss of consciousness and muscle spasms or other involuntary movements. Many conditions can produce epilepsy. For example, a genetic predisposition is

"Ganacity"

If there's one word that I will never forget from my AGSB experience, it's "ganacity"! A word frequently mentioned by our FinMan professor. What does it mean? It's a combination of the tagalog word "gana" (appetite, zest) and the english suffix "city" which converts an adjective word into a noun. 'Ganacity' therefore refers to one's state of desire or interest in something. I am sharing this because I feel that my 'ganacity' for what I am doing now is spiralling down, and it is so difficult to reverse it back up or just to keep it at a maintained level. It is becoming a struggle on a day to day basis. I am hoping that night and day will alternate fast so that this battle will end soon.

What to Think About this Holy Week

As we prepare for the coming week, let us be reminded again of this powerful message. In the message "Believe and Be Restored" we considered our need to believe that what God said is true. He said the death and resurrection of Jesus was the final sacrifice for our sin, and that those who believe would receive the gift of eternal life. Clearly, our Salvation is a gift from God; "For it is by grace you have been saved, through faith" (Ephesians 2:8). We did nothing to earn our Salvation and there is nothing we must now do to keep it, we simply must believe; "there is now no condemnation for those who are in Christ Jesus" (Romans 8:1). Though our sins are forgiven and Jesus is 100% sufficient for Salvation - though we walk in grace and are absolutely free of condemnation - sin in our life still causes temporary separation and tension in our relationship with God. Therefore, over and over in scripture, we are called to a life of holiness: "As obedient chi
