What is the relationship between caffeine and depression? Does caffeine make depression worse?
The exact relationship between caffeine and depression isn’t clear. There’s no evidence that caffeine — a mild stimulant — causes depression. However, some people are more sensitive to the effects of caffeine than are others. In such individuals, caffeine may worsen existing depression. How or why this occurs isn’t clear. But several theories exist.
· Although caffeine initially gives you a “lift,” it may later have the opposite effect as the effects of the caffeine wear off.
· Caffeine can make it more difficult to fall asleep and stay asleep. A lack of sleep can worsen depression.
· Caffeine appears to have some effect on blood sugar, especially in people with diabetes. Fluctuations in blood sugar can be associated with mood changes.

People with bipolar disorder are three times more likely than the general population to develop type 2 diabetes. Type 2 diabetes typically occurs in adulthood and is associated with insulin resistance, as opposed to type 1, which is usually diagnosed in childhood and is associated with insulin deficiency.
In a talk at the 2015 meeting of the Society of Biological Psychiatry, researcher Tomas Hajek reported that in a large group of bipolar patients, 13% reported a history of type 2 diabetes, 21% were diagnosed with type 2 diabetes upon laboratory evaluation, and 32.2% had pre-diabetes without realizing it. Thus, about half of these patients with bipolar disorder were either affected by diabetes or at risk for it, many without knowing it.
The Bad News
Diabetes complicates the course of bipolar illness. Type 2 diabetes is associated with poorer response to treatment, atrophy of the hippocampus, cognitive impairment, and higher rates of conversion from mild cognitive impairment to full-blown dementia.
The main effect of type 2 diabetes is insulin resistance. The body produces enough insulin, but insulin’s effects at its receptors are impaired. Diabetes also causes deficits in growth factors, increases in the enzyme GSK3B, decreases in mitochondria and brain-derived neurotrophic factor (BDNF, which protects neurons), and glucose toxicity.
Recent research by Hajek and colleagues shows that diabetes has several other detrimental effects on the brain in bipolar disorder.
On magnetic resonance spectroscopy (MRS) scans, people with type 2 diabetes had lower levels of NAA, a marker of neuronal integrity, in the prefrontal cortex. This can indicate impaired functioning. People with type 2 diabetes also had lower levels of creatine, indicating impaired energy metabolism. In addition, hippocampal volume decreases with aging, and type 2 diabetes accelerated this age-related decline.

In The New York Times (Health), they reported that women who have undergone bariatric surgery are more likely to deliver premature babies than those with low birth weight, a large new study shows.
The research looked at roughly 15,000 births that took place in Sweden between 1992 & 2009, including about 2,500 women who had had weight loss surgery. On average, the women delivered about five years after the surgery.

Managing diabetes can be tough enough, but the challenge is even greater when you’re under stress.
The American Diabetes Association says possible impacts of stress on diabetes management include the risks of:
- A sudden, dramatic rise in blood glucose levels.
- Strong negative emotions.
- Difficulty making decisions or thinking clearly.
- Compulsive eating or making unhealthy food choices.
- Significant strain on the heart and circulatory system.
