Blood in stool still?

I just researched the epression because my father has the same problem. Here is what I found:
Deficiencies in a number of minerals can also cause depression.

Magnesium: Deficiency can result in depressive symptoms, along with confusion, agitation, anxiety, and hallucinations, as well as a variety of physical problems. Most diets do not include enough magnesium, and stress also contributes to magnesium depletion
Calcium: Depletion affects the central nervous system. Low levels of calcium cause nervousness, apprehension, irritability, and numbness.
Zinc: Inadequacies result in apathy, lack of appetite, and lethargy. When zinc is low, copper in the body can increase to toxic levels, resulting in paranoia and fearfulness.
Iron: Depression is often a symptom of chronic iron deficiency. Other symptoms include general weakness, listlessness, exhaustion, lack of appetite, and headaches.
Manganese: This metal is needed for proper use of the B-complex vitamins and vitamin C. Since it also plays a role in amino-acid formation, a deficiency may contribute to depression stemming from low levels of the neurotransmitters serotonin and norepinephrine. Manganese also helps stabilize blood sugar and prevent hypoglycemic mood swings.
Potassium: Depletion is frequently associated with
depression, tearfulness, weakness, and fatigue.

If he is loosing blood (yes - quite common) you should check into his iron levels.
... but all minerals should be checked!

I was diagnosed stage IIIa in February of 07. Blood in the stool toward the end of treatment- not copious amounts but a little was a way of life for me - your entire digestive system is upset - but talk to your doctor about this. Depression at the end of treatment is common and normal - you are leaving the womb, so to speak, I was warned about it during chemo, I said "no problem", I was so wrong. I saw a therapist during treatment and started taking zoloft. At the end of treatment they upped they zoloft which helped tremendously. It is a totally common thing to have happen, urge your husband to seek treatment.

When I was on folfox with Avastin I got a bad intestinal infection...with blood and mucous. I was given antibiotics and also taken off folfox (because of bad neuropathy). It did clear up. I'm on folfiri and have seen occassional blood. Our intestinal lining takes a beating from chemo. Plus Avastin is a concern for bleeding issues. Mention it to your dr.

As for depression, there are many causes, but I would not forget to attribute the damage that the chemo itself does. The longer you are on it, the more cumulative the effects. Just like the fatigue that takes a while to set in, so with me with the depression. Mine always subsides the further out I am from a treatment and when I get two weeks off or more, it feels like a fog is lifted and I have more zeal for living. I would agree though with the nutrient deficiency perspective. Besides everything else, chemo can deplete our bodies of minerals, etc. And the body needs good nutrition to combat the chemo that kills good cells and bad cells. And, finally, yes, dehydration, which often goes unnoticed is a factor. I have experienced that too, including fatigue associated with it.

So be patient. The depression will pass. Oxaliplatin is pretty strong stuff. It will take a while for the body to get rid of it after his treaments stop, but it will, and the depression should improve.

I am such a believer that depression is often associated with physical causes. Find the causes. Don't only treatment symptoms. When I realized it was largely the chemo that caused the depression, I could overcome the feeling that there was nothing to live for, nothing I wanted to do, or that it was my fault.
